Hide “Back to Default Editor” in YOOthme Pro (Joomla)

In Joomla 5 and Joomla 6, go to the active administrator template (“Atum”) and check whether a file named “user.css” exists in the CSS folder (the path is “/media/templates/administrator/atum/css/user.css”). If the file does not yet exist, create it.

Add the following CSS to this file:

.view-article.layout-edit .adminform .tm-editor > a.tm-link {
display: none;
}

Click on “Save & Close” in the toolbar.
