WYSIWYG Broken, Unable to edit after creating field group.

Can’t edit pages/posts in admin area after activating ACF. Didn’t notice until after I created a field group. Thought it might be the rules issue that was mentioned here before, went back to edit the group and can only edit the title, nothing else loads.

Disabled all other plugins to no avail. Very disappointing.
