Editing problem???

So I've been busy trying to do some edits here on the pages to clean them up and what not, and I keep coming across some kind of error and a msg from our "main" admins saying that the editing section of our wiki is down. Has anyone else received this message? I haven't gotten it for every single page I have been working on but I want to say 1 out of every 4 pages it is doing this to me. It doesn't seem to matter which section I am working on, or if its a minor edit.
