Don't know. I've been trying to troubleshoot it. Got interrupted in the middle because Jenny had a medical appointment. There does seem to have been some low-level attack probing going on, but nothing super sinister. I have temporarily disabled logins. What did seem to be the biggest problem was that the wordfence plugin (a security plugin) was completely bogged down, taking forever to run. I've disabled it, and everything is zippy again. Of course, it's a security plugin, so that may leave us vulnerable. I'm wondering if its database got corrupted or something...
