Subject: Re: [MTT users] MTT server side problem
From: Pavel Shamis (Pasha) (pasha_at_[hidden])
Date: 2008-05-07 04:49:15


Hi,
I upgraded the server side (the mtt is still running , so don't know if
the problem was resolved)
During upgrade I had some problem with the submit/index.php script, it
had some duplicated functions and some of them were broken.
Please review the attached patch.
