Hello, I would like to take up the topic again. I had not received a notification at the time that an answer came and just remembered that I had already posted.
Divi is a premium theme by Elegantthemes. If I want to give a user role permissions on the theme, I get the following message:

Not Found

The requested URL /wp-admin/et_divi_options was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

The links or the areas are the following, which I would like to share:

This is what WP Admin looks like:

Interestingly, the Divi Theme also has user rights for various user roles. But for this user group everything is active.

How can I do this with the User Role Editor that the user roles I created can access it?

I thank you for the attention and thank you in advance for the reply.

Best regards
