Hi team
Since the joomla update 3.8.13 today I get a number of warnings like this on the frontpage:

Warning: count(): Parameter must be an array or an object that implements Countable in /customers/4/d/3/http://whoisontour.org/httpd.www/plugins/system/helix3/core/classes/menu.php on line 258 (and on the admin part on line 319)

Any idea how to fix this?
