Upgrading from the vB3.x Version
This is actually very easy. If your still using the old version, and you want to just migrate your old code over to the new templates, just change these things in the Tab Content code you added to your two templates.
In headinclude:
Change both instances of
to
Code:
{vb:raw vboptions.bburl}
In postbit_legacy:
Find each instance of
in the tab code, and replace them with
Code:
{vb:raw post.postid}
Now edit your existing content code if necessary, since they also probably use new values.
