Help with PHP and Errors

Good morning all,

I was wondering if someone could help me. I have been using WordPress 2.0 for a couple months now, without trouble. Yesterday I decided to create a photo gallery and then use a plugin to fetch images from said gallery to display on my main pages.

For every section that I do this I receive the following error at the bottom of the page:

Warning: mysql_affected_rows(): A link to the server could not be established in /home/rooftopr/public_html/gossip/wp-includes/wp-db.php on line 159

It actually displays like ten times.

What confuses me is that everything actually loads properly. There is no problem with the pictures that are grabbed.

The gallery I am using is Coppermine. The plugin I am using to get the pictures is Coppermine Fetch. I have the Exec-PHP plugin turned on to manage PHP on my site.

Any help would be great.

Thanks,

Billy
