Cookie Settings - vBulletin 3.6.1 & PhotoPost 5.3.1

[Al3xy]

I've been experiencing problems with cookie settings regarding integration of PhotoPost into vBulletin. Would someone kindly point me to the right direction to get this issue resolved ?

The only way I could login is via http://www.mydomain.com/forum/admincp

Logging into the username box either on the forum's page (http://www.mydomain.com/forum) or the photopost's page (http://www.mydomain.com/photopost) would throw me into a loop.

Is there a simple way to fix this problem or do I need to insert some syntaxes into the database. I don't know anything about phpMyAdmin, and I'm using cPanel to do some mundane stuffs like dropping or emptying the databases.

Below are settings for vBulletin and PhotoPost's configs:
-----------------------------------------------------
vBulletin path: /home/mydomain/public_html/forum
PhotoPost path: /home/mydomain/public_html/photopost

vBulletin URL: http://www.mydomain.com/forum
PhotoPost URL: http://www.mydomain.com/photopost

vBulletin prefix: vb3_
PhotoPost prefix: pp_

Forum Cookie Prefix: bb
vBulletin Cookie Path : /
vBulletin Cookie Domain: .mydomain.com

PhotoPost Cookie Path : /
PhotoPost Cookie Domain: .mydomain.com

Your cookie prefix must also read bb in photopost cookie settings

You must also have the correct vbulletin license number in the config settings
