I modified this code to work with the javascript better:
Add to any template on your main page (like the header or forumhome template):
Code:
<script language="Javascript">
function who(forumid) { window.open("misc.php?action=whopostedforum&forumid="+forumid, "whoposted", "toolbar=no,scrollbars=yes,resizable=yes,width=230,height=300"); }
</script>
Then, change the link you modified in "forumhome_forumbit_level2_post" to:
Code:
<a href="javascript:who($forum[forumid])">$forum[replycount]</a>
