If some apps aren’t working on your website, there could be several reasons. The most common issues include JavaScript errors, which can break app functionality. Browser extensions like ad blockers may also interfere with scripts. Another cause might be incorrect Content Security Policy (CSP) settings that block external resources. Outdated libraries, such as old versions of jQuery or React, may lead to incompatibility. If you're using embedded apps like Google Maps or payment gateways, invalid or expired API keys could be the issue. Network problems or misconfigured Cross-Origin Resource Sharing (CORS) settings may also stop apps from loading correctly. To fix these problems, check the browser console for errors, review your embed codes and CSP settings, and update any outdated scripts. Always test across different browsers and devices to ensure full compatibility.
