ERROR: Unknown error updating role-specific URL for role contributor | Peter's Login Redirect | Forum

Hi Peter,
I am getting the error "ERROR: Unknown error updating role-specific URL for role contributor". My site is set up as http://test.domain.com.

I followed the link on your plugin page about adding domains to the “allowed redirect” list.
I added this to my functions.php file.

function add_allowed_redirect_hosts( $hosts )
{
$allowed_hosts = array();
$allowed_hosts[] = 'test.domain.com';

// Add lines similar to the one below, one for each host
// $allowed_hosts[] = 'www.facebook.com';

return array_merge( $hosts, $allowed_hosts );
}

add_filter( 'allowed_redirect_hosts', 'add_allowed_redirect_hosts', 10, 1 );
?>
Can you help, please? Thank you.
