Make sure that the theme you've uploaded is compatible with Joomla 4. Some themes might be designed for older Joomla versions and may not work correctly with Joomla 4. Ensure that your server is running a compatible version of PHP for Joomla 4. Joomla 4 requires PHP 7.2 or higher. Make sure you're not using an outdated PHP version. Sometimes, conflicts with third-party extensions can cause errors. Try temporarily disabling any installed extensions and see if the issue persists.

Stop using Themler, it doesn't work with Joomla 4, and support has no interest in making it work. I did a fresh installation of Joomla 4 and imported a new template just downloaded and still I have an error when activating the menu, there is no way to put a menu unless you put a custom module with your links as a plain text, nothing functional . Themler's attitude towards his clients is unfortunate.

happy wheels Verify that the PHP version on your server is appropriate for Joomla 4. PHP 7.2 or later is required for Joomla 4. Verify that you are not running an out-of-date PHP version. If the issue still exists, try momentarily disabling any installed extensions.

Hello,
Check Theme Compatibility: Ensure that the theme you’ve uploaded is compatible with Joomla 4. Some older themes might not work seamlessly with the latest version. Official Site

Clear Cache: Clear your Joomla cache to ensure that any outdated data isn’t causing conflicts. You can do this by navigating to “System” > “Clear Cache” in your Joomla admin panel.
Review Extensions: Disable any third-party extensions or plugins temporarily and see if the error persists. Sometimes, incompatible extensions can lead to such issues.
Check Overrides: If you’ve made any template overrides, review them for any custom code related to the “isAdmin” method. Incorrect overrides can cause unexpected behavior.
Update Extensions and Joomla: Make sure that all your extensions (including the theme) are up to date. Also, ensure that you’re using the latest version of Joomla .
Debug Mode: Enable Joomla’s debug mode to get more detailed error information. You can do this by editing your configuration.php file and setting public $debug = true;.
Inspect the Code: Look into the theme files and check if there’s any direct call to the “isAdmin” method. If so, ensure it’s correctly defined.
