Hello,
after upgrade PHP to 7.2 I receive this error message when open all article:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/editfi5/public_html/editnews/components/com_k2/models/item.php on line 763

Before and after article like here:
editfiume.info/editnews/politica/3632-il-fronte-dei-lavoratori-punta-in-alto

What I can do?

Hi Igor,

This is just a warning, not error.
As a quick solution, go to Global Configuration > Server
Set Error Reporting to None

This will hide the message.

Then, you can try to update K2 to the latest dev release, this warning should have been resolved.

Thanks to all. In the end I put 2.9.1 and all is fine
