Maybe the place to look at is the other navbit templates. You can do soemthing to find out, in the vBulletin options, General options, and you'll see an option that says: Add Template Name in HTML Comments

Enable that ption, and go to the messgae page, chech the source code, and find the name of the template, once you do this, you'll know where to add the $navbar2 variable in the template.

I'll try this out.

EDIT:
In the STANDARD_ERROR Template something must be edited in order for it to get the navbar2 working, but I'm sure the error templates must be modified for this to work. I'll keep further investigation
