Error after installing Doctor theme

I imported demo content, but am getting an error of: Warning : count(): Parameter must be an array or an object that implements Countable in /homepages/29/d748649681/htdocs/clickandbuilds/ReeferMadness/wp-content/plugins/doctor-toolkit/shortcodes/sc_gallery.php on line 46

How do I fix this?
