If you recently upgraded to WP 3.3 and also run the popup domination plugin – you most likely received an error on your site. Renaming that plugin folder removed the error – but also meant you couldn’t use the popup domination plugin.
TO FIX open the popup-domination.php file, search for this line of code (it was on line 64 in my version) (you can either go to Plugins > Editor and choose popup-domination and find this file to edit, or log into your site via FTP and browse to wp-content > plugins > popup-domination and download this file, edit in the html editor of your choice and re-upload via FTP):
