Ok, I've been helpin someone out by installing hacks on their ubb board. I have installed 21 hacks in the past couple days and I didn't notice this problem until I was done!
K, here's the problem: When a new user registers they and the admin get an email with their logon info, well for some reason the info is blank now. Also when a user receives a PM an email is sent telling them about the PM and it is supposed to show the text of the PM but again that info is blank now.
Here are the Mods that are installed. It's running 6.2.1.1 on an internal network (can't access it from the internet). I can put publish any files you need to look at on an external website if desired. PLEASE HELP!

Thanks in advance! If you can't tell me exactly how to fix the problem can you at least tell me which files the emails get the info that is blank from? Maybe then I could back track the hacks that effected that file/s.
