Thanks for the quick reply, Paul. I did what you said, and the errors disappeared so long as BP was disabled. They came back as soon as I re-enabled it. But at least now I have super-admin access again. I had to disable all the plugins to get that to happen.

I did a mysqlcheck on the database – nothing needing repair.

Maybe one of the other developers modified BP core? Well, no worries for now. We have another instance of the site that we might try to mirror.
