You fisrt need to have your forums updated to 3.6.7 (3.6.6 minimum) Then when you login to your admincp there will be a message on the top saying something like

There are currently XX customized template(s) that need to be updated or reverted. Some sections of vBulletin may not function if you do not do this!

Click here to view these templates!

Click on the link and it will take you to a menu with all the outdated templates.
For this hack you are interested on updating
postbit, postbit_legacy, navbar, and memberinfo
so click on "[View History]" on those templates, and you will be able to compare the changes between the templates.
You will have more yellow lines depending on how modified your template is, but you are looking for green and reds. and specially the ones called $template_hook_[var] or something like that. If you don't want to revert your template, you will have to add these hooks to your current template manually.

Once added the template hooks, this modification should work no problem ^^. In addition if you want to update all your templates, it is very useful to use the modification post of vbulletin here to determine the importance and the nature of the updates
