Critical error - After login

[infrontweb]

I receive the following after logging in...

Critical error
There was an error while processing a database query

Using the latest release of CPG 1.4.18. Do you have any ideas for me? Thanks in advance.

Enable debug mode in config and post the mysql error message (not the entire debug output) you get when you replicate the error. If you can't get into admin mode use http://coppermine-gallery.net/tutorial/debug_mode.php.
