I am having serious trouble with widgets in the backend:
when I drag’n’drop a widget onto a dynamic sidebar, the widget collapses and only ‘delete’,’close’ and ‘save’ buttons are visible. All form fields are hidden. When I save those “invisible options’, widget expands and displays all form fields correctly.
This happens only on my theme, when I switch the theme, widgets work correctly.
I tried to comment-out most code from functions.php and theme files (hooks/filters/etc.), but widget behaviour in the backend is the same.
Did anyone had this kind of problem?
It’s not that: ajax is executed properly (200 OK). I believe this is front-end only problem (jquery), but can’t figure it out
Removed them (1 of them, to be precise) but still the same.
