You seriously need to upgrade

You are using v1.3.7.1 which was released in 2007.

The problem you mention was fixed in 1.3.9 and 1.5.0

And the bugs in your old version also required modifying many files to FIX them.
It's difficult for me to remember what lines were changed to fix your specific problem, especially when it was 6 years ago.

In the past 6 years since you installed your version, thousands of lines of code have been improved/fixed/changed, and you've ignored them all. The task simply gets bigger every day that you ignore it.
