In XOOPS 2.0.7 go to edituser.php look around line 185 for this line.
$cookie_radio_value = empty($HTTP_COOKIE_VARS[$xoopsConfig['usercookie']]) ? 0 : 1;
Just switch the 0 and the 1 so it looks like this
$cookie_radio_value = empty($HTTP_COOKIE_VARS[$xoopsConfig['usercookie']]) ? 1 : 0;
That should do it.
