I just installed Joomla 4 (Beta 7) today for a site I'm building for myself. Figured I should probably look at what they've done. Not sure I like the new layout. Everything takes far longer to do, but maybe it's just because it's new. Anyway... I now go to JCE, Editor Profile, Default, and, where are my options? There's only one page, no tabs, no options. Can't set page width and height, no way to allow/disallow JS, PHP, etc.
What happened?
