Error when terms are changed

Seems to me that this issue is related to this one #1300930: Array passed to user_load() causes warning and looks like has been fixed in dev version.

Looks like the module was loading the user in the old D6 fashion way.

Try to change this line of code in the legal.module line 586:

function legal_login_submit($form, &$form_state) {
  global $user;
  $values = $form_state['values'];
  $user = user_load(array('uid' => $values['uid']));

For this one

function legal_login_submit($form, &$form_state) {
  global $user;
  $values = $form_state['values'];
  $user = user_load($values['uid']);

Please report if that did the trick.

also got this warning..
is someone tried #1 code??

OK, it's worked, no more warning.
Data also recorded.

i read on the similar issue mention above, it's allready on dev
