Not the software, the pages & posts themselves. We just moved over to a new server, and since then, after an update, new post or page or whatever, the site will "revert" back to a different state. The same state it was in right before the move.
I thought it was the BackWPUp plugin doing it, but I deactivated it. This morning, however, I found it activated again, and again the old version was up. This is NOT making my client happy. We're probably going to have to go back to the old server for the time being while I try to figure out what's wrong with the new server version.
Any idea what could be causing this? I can't figure it out, and if I can't even deactivate what I think might be the main culprit, then the site will be rendered unupdatable, and useless.
