thread does not appear and a white plain page appears instead

[Hareth]

Dear Sir,
When a member or admin add a long new thread in the forum, the thread does not appear and a white plain page appears instead as if the person did not write anything. This is occurring frequently, although, there are threads even longer from them appears well. This problem has started with the use of the new editor CKEditor.

Regards,
