I recently upgraded and everything seems to be working correctly, except one thing. When I log in, I get a critical error stating "There was an error while processing a database query". But when I refresh my browser, I get a warning stating I'm already logged in and I can see all the admin tools. I can add albums, update, upload, change the config file. Everything works, except when I select "Album List", I get the same critical error. If I log out and refresh the browser the album list pops up?? I can do everything the administrator is allowed to do, with the exception of viewing the album list.
Did you remember to run update.php
If running update.php doesn't fix the issue, please enable debug mode (http://documentation.coppermine-gallery.net/en/configuration.htm#debug_mode) to get an extended error message.
