@robk: Go to the WordPress downloads area and it should have the old versions.

nicollb — just curious. You mentioned you have two other sites that were unaffected. Did you also upgrade those at the same time you upgraded the affected site to 2.8.2?

Also, to clarify — someone else pointed this out on another of my posts — by replacing the “root files” I mean the files in the top-level folder. Replace them all but the wp-config file.

I meant all the files in the top-level folder. (sorry — poor editing!) I replaced them all expect for the wp-config file (of course).

If you don’t have a backup, I imagine that if you download a fresh version from WordPress and recopy the files and folders listed above (being careful NOT to overwrite your wp-config file!), that would probably work, too. PIA, I know, but that’s all I know to do until someone else figures out the source of the problem.

I also deleted all my bad users.

I fixed the problem by reuploading the root files, the wp-admin folder and the wp-includes folder from a backup of the site that I made a week ago. I didn’t touch the content folder.

Same here. I’m going to start by deactivating plug ins. Have any of you changed or upgraded a plug-in recently?
