Try this:

in your "inc" directory find the file db.inc.php. In that file find the line that reads:

$this->link = @mysql_pconnect( $this->host . $this->port . $this->sock, $this->user, $this->passwd );

and change it to:

$this->link = @mysql_connect( $this->host . $this->port . $this->sock, $this->user, $this->passwd );

Taking out the "p" from mysql_pconnect makes it a single connect instead of a persistant connection.
