I followed your instructions and checked for JavaScript errors in the console while attempting to add or update a lesson. Below are the errors I encountered: 1. **React Warnings**: * ```wp-block-code Warning: You are importing createRoot from "react-dom" which is not supported. You should instead import it from "react-dom/client". Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. ``` 2. **jQuery Migrate Warnings**: * ```wp-block-code JQMIGRATE: jQuery.fn.click() event shorthand is deprecated JQMIGRATE: jQuery.fn.submit() event shorthand is deprecated JQMIGRATE: jQuery.fn.change() event shorthand is deprecated ``` 3. **TinyMCE Errors**: * ```wp-block-code Uncaught TypeError: Cannot assign to read only property 'submit' of object '#' ``` 4. **Unhandled Promise Rejections**: * ```wp-block-code Uncaught (in promise) Error: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received ``` * I’ve also uploaded the console log to a Google Drive folder for your reference: [Google Drive Link](https://drive.google.com/drive/folders/1AOlqWBWg68Rm8AZkLSRatLiXG55FkWSx?usp=drive_link) * Additionally, I noticed that the error occurs when using the TinyMCE editor for adding lessons, and it seems to be related to an attempt to modify a read-only property. * Could you please provide guidance on how to address these issues? I’m currently running PHP 8.3.6 but can downgrade to PHP 8.1 or 8.0 if necessary. * Thank you for your assistance! * Best regards, Abdelrahman Viewing 1 replies (of 1 total)
