    @zaasmi said in Google Custom Search API Key and CX ID to be configured: Would you like to show how to add a “Loading Spinner” to the HTML so users know the search is happening? A loading spinner is essential for a good user experience. Without it, the user might think the app is broken while the Python backend is busy talking to Google’s servers. Here is how to add a clean, CSS-only spinner that appears during the search and disappears once the image loads. 1. Add the CSS Spinner Add this to the <style> section of your index.html. It creates a classic rotating ring. /* The Spinner Animation */ .loader { border: 4px solid #f3f3f3; border-top: 4px solid #3498db; border-radius: 50%; width: 30px; height: 30px; animation: spin 1s linear infinite; display: none; /* Hidden by default */ margin: 10px auto; } @keyframes spin { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } } 2. Update the HTML Place the loader div right above your gallery so users see it immediately after clicking search. <div id="loader" class="loader"></div> <div class="gallery" id="gallery"></div> 3. Update the JavaScript Logic Modify your performSearch function to toggle the loader’s visibility using display: block and display: none. async function performSearch() { const query = document.getElementById('searchInput').value; const loader = document.getElementById('loader'); const gallery = document.getElementById('gallery'); if (!query) return; // 1. Show the loader loader.style.display = "block"; try { const response = await fetch(`http://127.0.0.1:5000/search?q=${query}`); const data = await response.json(); if (data.url) { const card = document.createElement('div'); card.className = 'card'; card.innerHTML = `<img src="${data.url}"><p>${query}</p>`; gallery.prepend(card); } } catch (error) { console.error("Error fetching image:", error); } finally { // 2. Hide the loader (whether it worked or failed) loader.style.display = "none"; } } Visualizing the Feedback Loop The loader bridges the gap between the user’s action and the server’s reaction. Why this matters for your Google API Because the Google Custom Search API can sometimes take 1-2 seconds to respond, a “silent” screen makes users click the button multiple times. Each click could potentially trigger a new API call, wasting your 100-query daily limit. The spinner tells the user: “I’m working, please wait.” Final Pro-Tip: Debouncing If you want to be extra safe, you can disable the “Search” button as soon as it’s clicked so the user cannot trigger multiple API requests until the current one finishes. // Add this inside performSearch document.querySelector('button').disabled = true; // Re-enable it in the 'finally' block document.querySelector('button').disabled = false;

    @Maaz-Fazal said in Ghost Admin Login Error – "There was a problem on the server": User: “I’m trying to log in to my Ghost admin panel (/ghost), but after entering my credentials, the button spins and eventually shows a red banner at the top saying: ‘There was a problem on the server.’ I haven’t changed any settings recently. Is this a database issue or a bug in the latest version?” This error is a generic “catch-all” message, but in 90% of self-hosted Ghost installations, it is caused by one of three things: Broken Mail Configuration, Nginx Proxy Timeouts, or Database Connection Issues. The Primary Culprit: Device Verification (SMTP) Ghost recently introduced a “Staff Device Verification” feature. If you log in from a new IP or browser, Ghost tries to send a verification email. If your SMTP/Mail settings are not configured correctly, the request will hang and eventually fail with a server error. How to fix it: If you don’t need email right now and just want to get back into your dashboard, you can disable this check via your config file: Open your config.production.json file. Add or update the following security block: /var/www/ghost/config.production.json "security": { "staffDeviceVerification": false } Restart Ghost: ghost restart. Nginx Proxy Issues If you are using Nginx as a reverse proxy, it might be timing out before Ghost can process the login request (especially if the server is trying and failing to send that email mentioned above). How to fix it: Ensure your Nginx configuration includes the correct headers to pass the original request info to Ghost: Nginx location / { proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_pass http://127.0.0.1:2368; } Check the “Real” Error in Logs Because “There was a problem on the server” is vague, you should look at the actual error log to see the specific code (like ECONNREFUSED or Access denied for user). Run this command in your Ghost directory: ghost log If you see EmailError: Your mail server settings (Mailgun/SMTP) are wrong. If you see 504 Gateway Timeout: Nginx is losing connection to Ghost. If you see InternalServerError: Usually related to a database crash or a full disk. Summary Checklist Disk Space: Check if your server is out of space (df -h). Ghost can’t create session files if the disk is 100% full. Permissions: Ensure the ghost user owns the files: sudo chown -R ghost:ghost /var/www/ghost. Node Version: Ensure you are using a supported version of Node.js.

    @Thc-Vape said in Failed to connect to php.new: zsh: command not found: npm The error “zsh: command not found: npm” in your zsh terminal means the system cannot locate the npm executable. This typically happens when npm is installed but not in your shell’s PATH environment variable, or if Node.js (which includes npm) is not installed or not correctly configured. To resolve this, you can either add the npm directory to your PATH or reinstall Node.js and npm. Troubleshooting Steps: Verify Node.js and npm Installation: Open your terminal and type node -v and npm -v. If you see version numbers, it means Node.js and npm are installed. If you get “command not found”, proceed to install Node.js and npm using your system’s package manager (e.g., brew install node on macOS with Homebrew) or from the official website.

    In that case, this would be an issue with the Plugin Check plugin, not with this GitHub Action. Issues with the plugins hould be reported at https://github.com/WordPress/plugin-check/.

    @full-stack said in Error: API error: Expect Google\Protobuf\Value.: Error: Server configuration error: Google Cloud SDK not properly installed The “Error: Server configuration error: Google Cloud SDK not properly installed” message typically indicates a problem with the Cloud SDK installation on your system. This can stem from various issues, including incorrect Python configuration, firewall restrictions, or conflicts with existing installations. To resolve this, ensure you have a compatible Python version, check your firewall settings, and consider reinstalling the SDK with proper configuration. Here’s a more detailed breakdown of potential causes and solutions: Python Configuration Issues: Incompatible Python Version: Cloud SDK has specific Python version requirements (e.g., Python 3.5-3.7, 2.7.9 or higher). Ensure your system has a compatible Python version installed and that the CLOUDSDK_PYTHON environment variable points to the correct executable. Incorrect Python Path: The CLOUDSDK_PYTHON variable should point to the Python executable, not just the directory. Python Conflicts: If you have multiple Python installations, especially older versions, it can lead to conflicts. Consider removing or disabling older Python versions. Firewall and Proxy Issues: Firewall Restrictions: Your firewall might be blocking access to necessary components during installation. Ensure that dl.google.com is allowed in your firewall rules, especially if you are behind a proxy. Proxy Configuration: If you’re behind a proxy, configure the http_proxy and https_proxy environment variables correctly, ensuring they use HTTP and not HTTPS. Installation Problems: Existing Installations: If you have previously installed the Cloud SDK, it might be helpful to remove the old installation directory before reinstalling. Installation Path: Avoid spaces in the installation path for the SDK and Python. Installation Method: Consider using the self-contained versioned archives if you are behind a proxy or firewall. Component Manager Issues: If the Cloud SDK component manager is disabled, it might be due to installing the SDK through another package manager. Troubleshooting Steps: Verify Python Installation: Use python --version or python3 --version to check your Python version and ensure it’s compatible. Check CLOUDSDK_PYTHON: Use echo $CLOUDSDK_PYTHON and declare -p CLOUDSDK_PYTHON to verify the environment variable is set correctly. Inspect Firewall: Check your firewall settings to ensure access to dl.google.com. Reinstall the SDK: If other solutions don’t work, try reinstalling the Cloud SDK, following the official documentation and considering the points above. Update gcloud CLI: Ensure you are using the latest version of the gcloud CLI. Consult Documentation: Refer to the official Google Cloud SDK documentation for detailed installation and troubleshooting instructions. By systematically addressing these potential issues, you should be able to resolve the “Server configuration error” and successfully install the Google Cloud SDK.

    The error ServiceWorker registration error name: “InvalidStateError” typically occurs when attempting to register a Service Worker in a context or state that doesn’t support it. Here’s what it means and how to fix it: ⸻ 🔍 What Does InvalidStateError Mean? This error happens when: • You try to register a Service Worker on a non-secure origin (HTTP instead of HTTPS). • You attempt to register it outside the main thread or in an invalid lifecycle phase. • The browser is in a state where the Service Worker can’t be installed (e.g., page not fully loaded). ⸻ ✅ Checklist to Fix the Issue 1. Use HTTPS Service Workers only work over HTTPS, except on localhost (which is allowed for development). ✅ Make sure your site is served over https://. 2. Correct Path Check that the path to your service-worker.js file is correct and accessible. navigator.serviceWorker.register('/service-worker.js') Register After Page Load Always register the Service Worker after the load event or when DOMContentLoaded has fired: window.addEventListener('load', () => { navigator.serviceWorker.register('/service-worker.js') .then(reg => console.log('SW registered', reg)) .catch(err => console.error('SW registration failed', err)); }); Same Origin Policy Ensure your service-worker.js is on the same origin as your page. Cross-origin SWs are not allowed. 5. Browser Support Verify you’re using a browser that supports Service Workers. ⸻ 🛠 Example Fixed Code if ('serviceWorker' in navigator) { window.addEventListener('load', function () { navigator.serviceWorker.register('/service-worker.js') .then(function (registration) { console.log('ServiceWorker registration successful with scope: ', registration.scope); }, function (err) { console.error('ServiceWorker registration failed: ', err); }); }); } ⸻ ❓Still Not Working? If you’re still seeing the error, share: • The registration code. • The URL you’re running it on. • The browser and version. I can help troubleshoot it further!

    @zareen The “Uncaught TypeError: firebase.auth is not a function” error typically arises when the Firebase Authentication module hasn’t been correctly imported or initialized in your JavaScript code. Here’s a breakdown of the common causes and solutions: Missing Firebase Authentication import: Ensure you’ve imported the getAuth function from the Firebase Authentication module. JavaScript import { getAuth } from "firebase/auth"; Incorrect Firebase initialization: Verify that you have correctly initialized Firebase with your project credentials before attempting to use firebase.auth(). JavaScript import { initializeApp } from "firebase/app"; const firebaseConfig = { // Your Firebase configuration }; const app = initializeApp(firebaseConfig); const auth = getAuth(app); Conflicting Firebase script inclusions: If you’re including Firebase scripts directly in your HTML, ensure there are no duplicate inclusions or conflicts. Make sure that firebase-app.js and firebase-auth.js (or their modular equivalents) are included. Using outdated Firebase SDK: If you’re using an older version of the Firebase SDK, the firebase.auth() method might not be available. Consider updating to the latest version. Compatibility issues: If you’ve recently updated other libraries or are encountering unusual behavior, there might be compatibility issues. Check for known conflicts and consider using compatibility versions if necessary. Scope or context issues: In some cases, the firebase object might not be accessible in the scope where you’re trying to use it. Ensure that it’s properly defined and accessible within the relevant function or module. Asynchronous operations: If you’re calling firebase.auth() before Firebase has fully initialized, it might result in this error. Ensure that Firebase is initialized before attempting to use its services. Mixing modular and namespaced syntax: If you’re using the modular syntax (e.g., getAuth) in some parts of your code and the older namespaced syntax (e.g., firebase.auth()) in others, it can lead to conflicts. Stick to one syntax consistently throughout your project.

    Here is Fixes the Problem Ensure Each Page Has a Main Landmark Each page should include a main landmark to allow users to bypass repetitive blocks of content (such as headers or navigation) and quickly reach the primary content. This is essential for improving navigation, especially for keyboard-only users. • Use landmarks to define specific sections of the layout, such as the main content area. • A page should not contain more than one main landmark to avoid confusion in navigation. HTML5 vs. ARIA In general, it’s best to use native HTML5 elements over ARIA roles whenever possible. For instance, while ARIA role role=“main” is supported by most screen readers, it’s better to use the corresponding HTML5 element for clarity and compatibility. Good Example: Using Proper Landmarks In the example below, all content is enclosed within appropriate landmarks to ensure that different sections are clearly identified. <header> <div>This is the header.</div> </header> <nav> <div>This is the navigation.</div> </nav> <main> <div>This is the main content.</div> <section> <div>This is a section.</div> </section> <article> <div>This is an article.</div> </article> <aside> <div>This is an aside.</div> </aside> </main> <footer> <div>This is the footer.</div> </footer> Why It Matters Web pages often contain repeated content such as navigation menus, ads, or headers across multiple pages. For users who rely on keyboards for navigation, this repetition can lead to frustration, as they must tab through numerous elements before reaching the main content. By ensuring proper landmarks and skip links, you: • Reduce the number of keystrokes required to navigate the page. • Help users avoid unnecessary strain and fatigue, especially those with motor limitations or disabilities that prevent mouse use. Keyboard navigation without these enhancements can be slow and physically exhausting, particularly when it involves tabbing through large numbers of elements like links and buttons in the page header. Rule Description Every page must include a main landmark to provide users with a mechanism to bypass repeated elements like headers or navigation and jump directly to the primary content. Simple Algorithm The page must have at least one of the following: • An internal skip link • A heading • A landmark region Additional Resources Here are some resources for improving accessibility: • Deque University – Subscription-based training for accessibility. • WCAG ARIA11 – Guidelines on using ARIA landmarks to mark page regions. • G1 – How to add a link at the top of each page to skip directly to the main content. • H69 – Instructions for providing heading elements at the start of each section. You can also refer to the complete list of axe 4.10 rules. By following these guidelines, you can create a more accessible and user-friendly experience for all users, especially those relying on keyboard navigation.

    @Engrnaveed-Saeed said in Incompatible type in filter using a callable: “I’m encountering an issue where I get an ‘Incompatible type’ error when using a callable with filter(). The callable seems to work fine on its own, but when used within filter(), it throws this error. What could be causing this issue, and how can I resolve it?” The “Incompatible type” error in filter() usually occurs when the callable you’re using doesn’t return a boolean value. The filter() function expects the callable to return True or False for each element, indicating whether that element should be included in the result. Here are a few potential causes and solutions: Callable Not Returning a Boolean Ensure that the callable you’re passing to filter() returns a boolean value (True or False). For example: # Incorrect: The function returns the value itself, not a boolean def my_callable(x): return x # Correct: The function returns a boolean condition def my_callable(x): return x > 0 result = filter(my_callable, [-2, -1, 0, 1, 2]) print(list(result)) # Output: [1, 2] Incompatible Return Type If your callable returns a non-boolean value (e.g., None, a string, or any other type), filter() will treat all non-None values as True but may still raise type errors if the value is not expected. For example: # Incorrect: Returning a string (non-boolean) def my_callable(x): return "valid" if x > 0 else "invalid" # Correct: Return boolean def my_callable(x): return x > 0 Using Lambda or Other Callables Ensure that if you’re using a lambda or other callable types, they also return booleans: # Correct usage with lambda result = filter(lambda x: x % 2 == 0, [1, 2, 3, 4, 5]) print(list(result)) # Output: [2, 4] Conclusion To resolve the “Incompatible type” error in filter(), make sure your callable function returns a boolean (True or False) based on the condition that determines whether each item should be included in the result.
