Hi,
I had several errors on my vbulletin forum.
Then i decided to upgrade my forum from 4.2.1 to 4.2.2

And now i see these errors in middle of every page of my forum :

vBulletin Message
Unable to add cookies, header already sent.
File: /home4/abc/public_html/includes/class_core.php
Line: 5755

And i see these errors on top of every page :

I upgraded to 4.2.2 but still new upgrade has not helped me and these errors are coming again and again.

Vbulletin.org has helped me each time when i had any problems with my forum. I am sure that this time also you people will help me.

Please help guys.
