Yeah i'm having the same problem. It says to find this in showthread.php :
PHP Code:
if (!$getperms['canviewothers'] and ($thread['postuserid']!=$bbuserinfo['userid'] or $bbuserinfo['userid']==0)) {
show_nopermission();
}
if ((!isset($pagenumber) or $pagenumber==0) and $pagenumber!="lastpage") {
$pagenumber=1;
}
The second part of the code is not in the showthread.php... I looked everywhere...
