Hi mattkeys,
You’re right, looks like I just needed to update my version of the repeater addon. Once I did that it started working.
Thanks for making a sweet plugin!
I had the same issue.
In the plugin file “wp-login-box/out.php” change the form action method to match the action method of the theme my login.
For example my form action is /login/
<form name='loginform' id='loginform' action='<?php echo $home; ?>/login/' method='post'>
