I want my forum to be setup so that users use their email addresses to login instead of username. I did a search on this forum, and this is the closet to what I wanted:
https://vborg.vbsupport.ru/showthread.php?t=96832

This is for v3.5.0 RC3 and login with either username or email, but I have 3.8.4 PL1 and I want login with email only, not username.

I tried:
File: ./includes/functions_login.php
Line: 140
CHANGED if ($vbulletin->userinfo = $vbulletin->db->query_first("SELECT userid, usergroupid, membergroupids, username, password, salt FROM " . TABLE_PREFIX . "user WHERE username = '" . $vbulletin->db->escape_string(htmlspecialchars_uni($username)) . "'"))

TO if ($vbulletin->userinfo = $vbulletin->db->query_first("SELECT userid, usergroupid, membergroupids, username, password, salt FROM " . TABLE_PREFIX . "user WHERE email = '" . $vbulletin->db->escape_string(htmlspecialchars_uni($username)) . "'"))

It didn't seem to work. Can anyone help me with this? Thanks.
