Workaround

Don’t hesitate to make a full backup of your site before proceeding.

We have currently 5 possible workarounds:

1. You can use Advanced Translation Editor.


2. Alternatively, you can also install the Enable jQuery Migrate Helper (opens in a new tab) plugin.


3. You can click the Text tab and then return back to Visual tab in the Classic Translation Editor interface.


4. You can also:
   
   
   • Edit your  wp-config.php file.
   
   
   • Just after line:

     define( 'DB_COLLATE', '' );

   
   
   • Add this:

     define('CONCATENATE_SCRIPTS', false);



5. Finally, you can add the following snippet in your functions.php theme file.

   add_filter( 'wp_default_editor', create_function( '', 'return "html";' ) );
