I’m currently experiencing an issue with my WordPress site after upgrading to PHP 8.0 on a new server. I’ve already uploaded a PHP 8.0-compatible theme to my cPanel, but I’m unable to activate it due to a persistent error: **Deprecated: Required parameter $is_script follows optional parameter $list**. Additionally, my WordPress dashboard is not functioning properly. Your task will be to fix the WordPress dashboard error and ensure that the new theme is activated and fully functional without modifying its current design or features. Once the theme is active and running seamlessly, the job will be complete. Attention to detail and ensuring a smooth user experience is key.
