unregister.php issues

My unregister.php is messing up.  When someone click on it to go to that page it logs them out and ask them to log back in and creates an endless loop of login and it loging you out.  Does anyone know what could cause this?

I can't replicate this error. I simply click the account deletion button and it immediately logs me out and deletes my account, no endless looping of logging in.

I want to say permissions, but that's just because I have no other idea why this could be happening.

works here :)
try and re-upload a new one

Now I need to make a new boonex.us account...

LOL, sorry about that.  I know it is related to my install, but I can't for the life of me figure this out.  Has anyone mapped out which class this inherits info from, maybe I changed something there I shouldn't have changed.

I did upload a new one with the same issue, very weird.

I hope you're not asking your membership to be your test mice. 

Well, what kind of modifications did you make?

Dear God, what have I just done?
