 * Hi,
 * I’m debugging login issues and found an error in our logs for WP Bouncer:
 * [05-May-2017 13:52:46 UTC] PHP Notice: Undefined variable: ub in /home/gozen/
   public_html/wp-content/plugins/wp-bouncer/wp-bouncer.php on line 117
    [05-May-
   2017 13:52:46 UTC] PHP Notice: Undefined variable: ub in /home/gozen/public_html/
   wp-content/plugins/wp-bouncer/wp-bouncer.php on line 129
 * Any ideas what’s causing this?

 * After getting a chance to look at the code myself, it looks like `$ub` was misspelled
   as `$up` on line 72, causing all instance of `$ub` to be an undefined variable.
 * Can’t believe no one’s noticed that before!
