Thanks…tried that and it hasn’t changed anything. It seems to me that something from the parent theme (the BP default theme) is not getting called properly. Since the problem only started happening after I upgraded to WP3.1, I’m wondering if something in those files has changed…maybe in the definition of a default location…?
I actually did update to 3.1 and then updated the database. Everything was good until I then tried to update the Buddypress Links plugin. I received an internal server error in the middle of the update and then tried to do a manual update. That’s when everything shut down. Then, my host (GoDaddy) recommended reverting back to the earlier WP version. (They really are no help when it comes to WP. I wish I’d never hosted it with them, but I’m stuck with it for now.)
