Trouble logging in

[Kerrigan666]

I made some changes in my navbar template so we could have some custom links under the login box.
The links are the text "PSP Hack Guides Front Page - Contact Us - Archive - Bottom" you can see it
if you go to our site at http://psphackguides.com/forums.
Now when we try to log in, it won't work. It sends us back to the forum index without signing us in.
To make it work we have to check the little box that says "Remember Me". So we can still log in and use the forum..
We just have to check that box first. I realize it isn't supposed to remember us if we don't check it, but it shouldn't forget about us that quickly.

I don't have a lot of PHP knowledge, only HTML and a small amount of C programming knowledge.
I knew enough to figure out how to add the links... but now I think this problem is a little more complex than what I can fix on my own.

We are using vbulletin 3.8.6.


Thanks for any help!
