I just upgraded my server from PHP7.1.31 to PHP7.3.x yesterday as I was getting EOL warnings from Joomla. Since that, I can confirm that this K2 warning has now appeared,

Warning: count(): Parameter must be an array or an object that implements Countable in /home/tastewas/public_html/components/com_k2/models/item.php on line 763

While I understand that it's only a warning and only appears if the error reporting in Joomla is set to anything other than none or Sys Def, and it doesn't affect site operation, does this not mean that the K2 code isn't completely in line with current PHP versions?

Hello,
I just had an error preventing my site from working in frontend. The error is :

[02-Jan-2020 11:18:29 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in [...]/templates/sandal/html/com_k2/templates/default/item.php on line 187
[02-Jan-2020 11:18:33 UTC] PHP Warning: count(): Parameter must be an array or an object that implements Countable in [...]/templates/sandal/html/com_k2/templates/default/category.php on line 137

I can't figure out how to fix this problem when everything is working properly backend. Could you help me ?
