Whenever I go into the user admin and pull up the user I want to activate, then change the radio button to "Yes" beside the User is Active, then press Submit, I get the following error:

Template->make_filename(): Error - file error_body.tpl does not exist.

and it does not update the account.

This is also using the default SubSilver Template.
