For some reason, I have the session login be logged out when a user either:
1. clicks on the logo at the top left (leads to index.php) even though clicking on the prank link keeps the session active which also goes to index.php
2. user goes to the talk page

There is nothing on either of these pages that should make the sessions unset. The only time it unsets is if you set logout=1 in the url.

Here is a login you can use: 2685401

Any idea why this is happening?

http://tinyurl.com/6rlc6l thats the url by the way

do you have ....

session_start()

in the other pages?
