probably related to bug #12268

{FrontEndUsers action="changesettings"} with {cms_module_hint
module=FrontEndUsers changesettingstemplate='feu_change_single_field.tpl'}

calls the correct template. But on submit, i get redirected to the default
changesettings template, and the action script seems to run twice.

i chanced action.changesettings.php and commented out this line 

$this->redirect('cntnt01','changesettings',$returnid); 

Now the script seems to only run once, and I am not redirected to the
defaultsettings template. That hack may however break other things.

Thank you.
