Hmmm, I posted a reply to this last night and it is not posted here.
Anyway, it was a plugin conflict. Oddly, the site had been working fine with the plugin active, but all of the sudden it stopped working without any updates or changes. Not sure why it worked fine one day and didn’t the next.
Yes, found it was a plugin. Oddly the plugin has been activated the whole time, it just started causing the error after several days. Have to figure what changed.
Thanks for the help!
I just did that per your suggestion and it is a problem in Twenty Ten as well, so I guess this means there is something wrong with a WP core file or the db? What is your suggestion on where to start looking?
Thanks for your help.
