omg omg omg!
I did find the problem regarding VBSEO incompatibility after like 10 hours+ of works!!!

ADMIN CP >+Module & Products >+Module manager
Then MODIFY this module: VSa - Advanced Forum Statistics - FH
Try to find this (it,s under "case 3", somewhere in the file):
$vsatopstats_titlelink = 'showthread.php?'.$session['sessionurl'].$get_new_posts['threadid'].'&goto=newpost#post'.$get_new_posts['lastpostid']; break;
and change it to:
$vsatopstats_titlelink = 'showthread.php?'.$session['sessionurl'].'t='.$get_new_posts['threadid'].'&goto=newpost#'.$get_first_new_post['lastpostid']; break;

This should solve your problem!

If you are using "arrows" for first unread post, there will still be an incompatibility. Solving this problem is quite easy: just dont use arrow for "first unread post".
go to "ADMINCP >+SETTINGS > OPTION >+VSa Advanded Stats.
'Latest Posts' - Title Link -> First unread post
'Latest Posts' - Arrow Link -> Last post (or anything but FIRST UNREAD POST).

You wont have any problem with those settings!

Cheers!
