With WordPress 3.5, the prepare query has changed and i'm getting some errors with this plugin.
Some info is here: http://make.wordpress.org/core/2012/12/12/php-warning-missing-argument-2-for-wpdb-prepare/ and it seems this plugin needs some updates in order to work properly.
Now i can do this myself, but then i might break it with future updates, so is there any chance this plugin will be updated in the near future?
When adding or changing a user the errors i'm getting are:
Missing argument 2 for wpdb::prepare(), called plugins/register-plus-redux/register-plus-redux.php on line 2167, 2168, 2158 and 2191.
I hope this gets fixed soon.
