Assistance needed - cookie error?

[j2012]

I have V bulletin version 3.8.3 I think. The latest wordpress version. I am NOT savy in this field but I am trying to get this to work.

So, after I give the relative path to my forum, I get this message

"Unable to add cookies, header already sent.
File: /home/xxxx/public_html/wordpress/wp-content/plugins/vbbridge/vbbridge.php
Line: 35"

When I click "Back" it does state "Vbulletin has been located and is loaded into memory"

Any assistance is appreciate.
