My forum's ckeditor is unavailable in Firefox and IE when i upgrade from the Version 4.1 to 4.2. The error happens when i use the Language with UTF-8, but the Iso does not.
I tried to disable all mods and created some new styles but the error still appears. I don't know how to fix it (my forum is using UTF8 Lang). Somebody help me, please! Thank you so much !
