State shouldn't be required

[MarkPfennig]

$state = $wp_query->query_vars['state'];
...
if ($stateFromGet->interim) {

Lines 344 & 392

This assumes state is present, and assumes that it's a json_encoded object that always has an interim property. Due to this it throws PHP notices which if displayed prevent auth0 from redirecting.

State isn't always present, like when doing sso via /authorize.

Just use isset checks and it'll fix the problem :)
