Error when single category chosen

  • When a single category is chosen, an error appears on the page

    Warning: in_array() expects parameter 2 to be array, string given in /home/barefruit/hvg-fabrics.barefruit.com.au/wp-content/plugins/mixitup-portfolio-widget/mixitup-portfolio-widget.php on line 142

    Warning: in_array() expects parameter 2 to be array, string given in /home/barefruit/hvg-fabrics.barefruit.com.au/wp-content/plugins/mixitup-portfolio-widget/mixitup-portfolio-widget.php on line 202

    Also when the widget is opened in back-end, the chosen category is no longer preselected.

    Both can be fixed by adding the following code to mixitup-portfolio-widget.php:

    // cast $category_ids[0] to array if just a single category chosen
    if(!is_array($category_ids[0])) $category_ids[0] = array($category_ids[0]);

    Insert it twice, once on line #138 to fix the front-end error, and once on line #348 to fix the back-end.

    Can the author include this fix in the next version? Thanks
