Seeing an error on registration page when 'new blog templates' plugin is activated

Seeing the string "array(0) { }" posted above the registration form on this page: http://jono39.staging.wpengine.com/register/

running Wordpress MU 3.9 with gravity forms handling the registration

This is not happening on my live site : http://hubbli.com/30-day-free-trial/ using the same form
