This is actually pretty strange, when I am logged in as an administrator I can't even click the "Add Karma" button on adis.php (nothing happens when the button is clicked). When I logged in as a member it simply was the "not logged in error". Again, this is with the following fix:
Find the in your postbit template:
<a href="newreply.php?s=$session[sessionhash]&action=newreply&postid=$post[postid]"><img src="https://vborg.vbsupport.ru/images/quote.gif" border="0" alt="Reply w/Quote"></a>
Under it, place this code:
<a href="javascript

opout('adis.php?flag=$post[flag]&postid=$post[postid]&userid=$bbuserinfo[userid]&username=$bbuserinfo[username]&usergroup=$bbuserinfo[usergroupid]&usertitle=$bbuserinfo[usertitle]&post_userid=$post[userid]&post_username=$post[username]')"><img src="https://vborg.vbsupport.ru/images/postkarma.gif" border="0" alt="Karna"></a>
(tiny side note, your alt tag says "karna" not "karma")
