Log-in Loop

[LittleB@]

I do not know if I am allowed to look for help here really since it's vBadvanced-based but any way, I guess you could just delete my topic if it's not suitable.

I am stuck in a log-in loop. The problem looks as follows:

I can log in as normal and stay logged without any problems while using the forums, however when I try to access my cmps_index.php I am treated as a guest and prompted to log in. I enter my details and continue, I get the "welcome, log-in successful"-message and when the cmps re-appears it's just the same - I am no longer logged in and I have the option to enter my details again.

I've looked through options and made sure I have the url to my index correct, I reseted cookies etc but I still cant seem to solve this - any help is greatly appreciated.

Edit - never mind, problem solved. I had for some reason changed the default cookie prefix thus rendering the vBadvanced cookie useless
