Updated to PHP 7.2.4 and got error

Warning: count(): Parameter must be an array or an object that implements Countable in /var/www/html/site/wp-content/themes/anaglyph-lite/includes/admin/libs/metaboxes/init.php on line 756

Removing the code block on line 756 does resolve the issue but not sure if that breaks other features at the moment.

Seems to be related to new php functionality, any other fixes available besides removing the code? Thanks!
