Done. Repair status: OK.
This is a re-install. A long time ago, I had an older version of Photopost on the server, but it was using it's own database and installed in a different directory (/gallery), and I couldn't get it to work well so I took it off. This time around, I chose to use one common database for vBulletin and Photopost, installed it in a different directory (/photos). Do you think there may be some lingering settings, tables, code, etc that's messing with the new installation?
These are colocated servers running Linux 220.127.116.11-grsec on an i686 with Apache 1.3.36 (Unix), PHP 4.4.2 and mySQL 4.1.21-standard.
Hope that helps. Thanks.
