Get user role works only for administrator.

Hello everybody!

I’m trying to modificate “Members directory” plugin, so it shows up user role along with website/name/bio.

Here is my code:

Get user id:

$user_idd = $user_details->ID;

Get role of that user:

$user_current = new WP_User( $user_idd );
$role_container = $user_current->roles;

Display user role:

$content .= '<strong>' . __('Rank') . '</strong>: ' . $role_container[0] . '<br />';

The problem is that this code for some reason works only for administrator. When I go to members page and choose administrator, I’m getting “Rank: administrator”, but when I choose contributor or subscriber profile, I’m getting “Rank: “(empty string).

Any ideas ?

Thank you.
