    I am getting a php warning showing up in my logs, a simple code tweak will deal with it…

    Invalid argument supplied for foreach()
    /wp-content/plugins/wp-persistent-login-premium/inc/user-count.php:127

    $allowed_roles = get_transient(‘persistent_login_allowed_roles_reference’);
    foreach( $allowed_roles as $key => $value ) {

    In my use case, I have not set any of the allowed roles so the transient hasn’t been set yet. simply wrapping the foreach() in an if(is_array() && count()) will fix the warning.

    if(is_array($allowed_roles) && count($allowed_roles)){
    foreach( $allowed_roles as $key => $value ) {
