My VBulletin is screwy! Help!

[NinjaBen]

Hello i installed VBulletin 2.3.2 on to my server which is detailed as an:

Apache/1.3.29 (Unix) mod_auth_passthrough/1.8 mod_log_bytes/1.2 mod_bwlimited/1.4 PHP/4.3.3 FrontPage/5.0.2.2634 mod_ssl/2.8.16 OpenSSL/0.9.7a

We us CPanel for our server and we run MySQL version 4.0.15-standard.

I have installed multiple hacks from here including: Store 3.0 by lesane, Physical Iten Add on by Churchmedia, Stats by Afterburner, and Stats by Bane.

The problem is relatively new. The probelm is that SOME member's names do not show up in our second forum "Junk in the Trunk" Their Username does not show up on the "Thread Starter" column or the "Last Post" column (both with in the Forum and on the main page showing both forums). The odd part is that only a 2 member's names have not shown up so far, but some still do.

The problem can be found here:

Thank you in advance for your help!
