Comment (by volkerg):

 On our website, we recognize the same error:

 http://w-k-o.de/das-praesidium/ shows: Warning: count(): Parameter must be
 an array or an object that implements Countable in
 /homepages/28/d689728036/htdocs/clickandbuilds/WorldKennelOrganization/wp-
 includes/post-template.php on line 284

 It is a multilingual wordpress website with latest polylang, avada theme,
 and other updates. The error occures after updating the components. On php
 5.6 and on php 7.1 the german pages are not shown, the english pages are
 shown fine.

 Switching back to php 7.2 I got the same error again.

 If needed I can restore my backup and check if the error occures before
 updating, just changing the php versions or if it is result of an update.

 I am using WP 4.9.8 running AVADA Child Theme
