I really liked this mod and it was working on 3.7.2 but I've just moved to an new server with PHP 5.26 and it quit working. I have now upgraded to 3.7.3 but others say it works with the newer version so I don't think that is the problem.
I get this error code when I try to switch over to another user:
Code:
Unable to add cookies, header already sent.
File: /home/***/public_html/***/vbulletin/includes/class_core.php
Line: 3243
Any ideas as to the cause and fix?
