CMS Error during login
 

Just finished updating my forum to the publishing suite. (Coming from the latest 3.8.4)

Install went smoothly... until the last step where it asked me to login, I received this error:

Warning: fetch_template() calls should be replaced by the vB_Template class. Template name: post_thanks_navbar_search in [path]/includes/functions.php on line 3957

How do i fix?
