I'm not sure - no one else has had this problem. You can try adding forumrules to the globaltemplates cache...

Go to your Plugin Manager, edit the TGREER_invite_template plugin. Add the colored code:

global $globaltemplates;

$globaltemplates  = array_merge($globaltemplates, array('invite_forumrules'));

$globaltemplates  = array_merge($globaltemplates, array('forumrules'));
