I was trying to edit the HTML of my menubar in the Editor, and now all of a sudden I get this error message:
Fatal error: Cannot instantiate non-existent class: widget_comicpress_menubar in /homepages/28/d317709735/htdocs/wp-includes/widgets.php on line 324
If you want to see it for yourself, just try going to soulsymphonycomic.com.
It appears whenever I try to go to my website or even my WordPress control panel. I'm completely locked out. Can anybody help?
