Thank you for the suggestion, I just did that and I optimized the table. I also went in and found the 11 messages he had and deleted them and the problem remains. He now shows 0 messages but if I click on "Received Private Messages" I get this error - "Fatal error: Maximum execution time of 60 seconds exceeded in /home/httpd/vhosts/domain.com/httpdocs/lttd/mysql.inc.php on line 109" and it takes much longer than the 60 seconds it states.
Thanks for any help!
