Great mod! I need a PM module where you can send to multiple recipients.

It seems to work great for all users except UID1. When I visit http://www.mydomain.com/privatemsg/new I get the following error:

warning: call_user_func_array() [function.call-user-func-array]: First argumented is expected to be a valid callback, 'privatemsg_new' was given in /mypath/mydomain.com/includes/form.inc on line 218.

I am able to reply to existing PMs, but not create new ones (ie, no buttons for list, compose, contacts or manage folders). However, everything seems to work for other users. Maybe this mod isn't meant to work for UID1?
