MyBB Community Forums

I changed my primary domain name through my hosts and now when I click a link on my forum its linking to the old address so for example:

old domain: domainA.com
New domain: domainB.com

when I login its going to domainA.com/member.php?action=login

Hosts are saying the links are within MyBB and I have no idea how to resolve this

open ./inc/settings.php file and put correct forum url for $settings['bburl']
also put correct cookie settings in the same file. you can follow this guidance for cookie settings

after above changes, log into admin panel and again put correct forum url and cookie settings at the
general configuration settings.

worked great, thanks
