    When using object cache, sometimes the cache might be flushed and the persistent_login_user_count_temporary transient can return false. Triggering those:

    Deprecated: Automatic conversion of false to array is deprecated in /wp-content/plugins/wp-persistent-login/classes/wp-persistent-login-user-count.php on line 870
    Warning: Undefined array key 0 in /wp-content/plugins/wp-persistent-login/classes/wp-persistent-login-user-count.php on line 870

    Add a check to ensure the transient is set, otherwise initialize if as array() before taking actions on it.
