bbPress and Wordpress integration please login to post

I have integrated bbPress with Wordpress and it works fine on the development server but when I moved to production server, i开发者_JAVA百科t is now asking me to log on before posting new topic even though I was logged on in Wordpress side. I didn't have to log on separately with development server to post in the forum.

Is there something I need to change?

EDIT:

I found the answer! I had to add www in front of meta_value for url under object_type bb_option under bbpress_meta table!!!

It could be a cookie issue.

Make sure you have both installations set the cookie domain to be .yoursite.com - notice the . at the start, and the path to be /
