I've been using my blog for six months without issue. Then suddenly this evening I noticed that my TinyMCE Adv. editor was no longer showing in my post backend. I deactivated, reactivated, turned off the only plugin I had added recently, deleted it and installed again. Nothing worked.
Then I tried the same with CKEditor. It won't show either.
Both plugins seems to activate fine, Their settings area shows up in the menu bar on the left of the admin.. They simply do not show in the actual post writing page.
What could be happening?
