One of our users just clicked the "upgrade" button in the WP Admin interface (we were on 2.7) and now we're getting the following error in our PHP logs:
PHP Fatal error: Call to a member function read() on a non-object in /home/feld/public_html/wp/wp-includes/theme.php on line 387
I've removed all the plugins manually and that didn't help, I'm guessing it's something in the themes but I'm not sure where to start looking. Any ideas? The site is working currently but the admin tools aren't (so we can't post).
