DOH! Must’ve had a brain freeze. I disabled all the plug-ins, then reactivated them one by one until I found the miscreant. Problem solved. Thanks for the what-to-do reminder!!! [Yes – using the latest versions of plug-ins/WP/BP.]
I finally figured out that it isn’t a theme problem, but something more basic, so I’m starting a new topic. I have used WP successfully on at least a dozen sites, and have a reasonable familiarity with HTML, stylesheets, a tiny bit of PHP.
I did take it wrong at first, Jivany, but decided not to be a total idiot and snap at people who are trying to help.
