For those with vbAdvanced having trouble with this appearing correctly in your homepage navbar, here is the edit I found to fix it. Replacing the relative url with an absolute (full) url corrects this linking error.
Open the
cyb_advancednewposts template found under Cybernetic Templates.
Find instances of:
Code:
<a href="search.php?do=getnew
Replace with
Code:
<a href="http://YOURDOMAIN.com/forum/search.php?do=getnew
I replaced all 3 instances of the relative url with an absolute. Not sure all 3 were necessary but it worked for me.
