Recurring hang on line 283 of ckeditor.js:
Error message ref: "Script: http://war.spruz.com/dhtml/ckeditor4-4/ckeditor.js:283"
This is not site-specific, as it occurs on our premium sites also. Relates to checking background-color, I believe. Haven't had time to address this yet -- just throwing it out there.
Expected end of value but found 'undefinedpx'. Error in parsing value for 'background-position'. Declaration dropped.
