The Unregistered displays when the username field is left blank when the form is sent. The REMOTERR dislays when the email field is left blank. For some reason these started showing up in vB 4.0.
My workaround: to check for a blank username and email fields and if either are empty bypass the stopforumspam check, as vB will send the user back to complete these fields anyways. Just a work-around, I tested it and it seemed to work correctly.
Go to plugins and open the vbstopformspam plugin for register_addmember_process. Select edit, and highlight the code. Paste this over it:
Code:
if (!empty($vbulletin->GPC['username']) AND !empty($vbulletin->GPC['email']))
{
$sfsPurged = false;
require_once('includes/functions_vbsfs.php');
sfsProcess();
}
