    If You get this Error:

    Warning: count(): Parameter must be an array or an object that implements Countable in /wp-content/plugins/archives-calendar-widget/arw-widget.php

    than You need to change twice in arw-widget.php
    if(count($categories))

    into
    if(count((array)$categories))

    Cheers
    Henry
