Text isn't showing for me in the AdminCP -> Usergroup manager for me either
Edit 1: Or the UserCP
Edit 2: Also, you should change line 188 of plugins_usercountd.php to use $vbulletin->db->fetch_array() instead of mysql_fetch_array() as people like me who use MySQLi get:
Code:
Fatal error: Call to undefined function mysql_fetch_array() in C:\Program Files\Apache Group\Apache2\htdocs\vb_3.5.4\includes\plugins_usercountd.php on line 188
Thanks,
