Not sure why it's not working (showing).
I have done:
To get this product working you must set "Depth of Sub-Forums" to "1" in vBulletin Options > Forum Listings Display Options
-To set product options go to: AdminCP > vBulletin Options > VSa - Sub-Forum Manager
Screen Shot:
Depth of Sub-Forums
Sub-Forum Manager
My Forum View
I'm running VB 4.0.3
VSa - Sub-Forum Manager 3.0.1
Did I do something wrong?
Thanks for the help.
