Hello @Nene,
Thank you for providing the details. Your request is now much clearer.
You have the debug log enabled (https://prnt.sc/EpAbEH_O7J87), and currently, there is a notice displayed on your website’s frontend (https://prnt.sc/isg_iwKK3cLK). When such notices appear with debugging enabled, AJAX actions (or other actions) – such as loading settings in the Customizer – may be affected and fail to load correctly.
After setting define('WP_DEBUG', false);, the notices are no longer displayed. This configuration is highly recommended for live websites, as enabling debug mode should only be a temporary measure for troubleshooting rather than showing notices to all visitors. Once this change was applied, all sections in your Customizer loaded correctly (https://prnt.sc/KZUgLS56xyRO).
Please check again on your side.
Best regards,
Jack Richardson
