Have you reported problem with broken links to vBSEO authors?
I think this needs to be fixed on their side.
vBSEO converts:
Code:
showthread.php?1094&goto=newpost#post9784
to:
Code:
showthread.php?1094=&goto=newpost#post9784
I don't know why extra '=' is added, but it's done AFTER Adv. Stats links are generated.
So this is something which can not be fixed in VSa - Advanced Forum Statistics.
