When this plugin is active, and I register a new user...when I click on the Register page I get a blank screen...and nothing happens.
When I de-activate this plugin all works again.
I also use CIMY Extra Fields plugin, and have tried with New User Approve in all 4 variations (CIMY on NUA off, CIMY on NUA on, CIMY off NUA off, CIMY off, NUA on) and the problem only occurs when NUA is on.
