 * Dear Sir,
 * The isntalled plug (Controlled Admin Access) is not able to send email to user
   with login detail.
    I needed to setup new admin user with restricted access. 
   The password is generated but user email is not being sent out. When I try to
   login with the username / password on the admin panel it returns the following
   error message:
 * Warning: call_user_func() expects parameter 1 to be a valid callback, no array
   or string given in …(directory / function.php on line that defines user function
   as follows:
    Line 2680 call_user_func( $function, $message, $title, $args );
 * Could you please let me know how to resolve this?
 * Many thanks.
