Log file errors

My log file on a site I manage is filling up with these errors:

PHP Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /hermes/bosweb/web006/b67/sl.classof2k8/public_html/manager/includes/user_settings.inc.php on line 19
PHP Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /hermes/bosweb/web006/b67/sl.classof2k8/public_html/manager/includes/user_settings.inc.php on line 17

Same thing over and over.

Does anyone know what this is or what’s going on?

The site seems to be running OK, but I’m a little concerned about this.

Thanks.

Justin

This indicates a problem with your database, specifically with the modx_user_settings table. Did changes get made to your server recently, upgrades perhaps? Without more information, I don’t know what else to tell you.
