I installed the new K2 version 9 and now i get every time this. How can i solve the problem. Can someone help me out please

Try v2.10 (dev) from github.com/getk2/k2/archive/master.zip please.

Thank you so much. !!! It solves the problem.

Great :)

I have same I guess:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/rapigukk/public_html/templates/bemax/html/com_k2/blog-list/item.php on line 228

The master file didnt helped...any idea ?

That's because your overrides for K2 in your template require some changes. Just compare the files with errors with the source K2 template files and pass along any changes to the ones in your Joomla template.

You've got me stumped.

So I should check from my template this:
bemax/html/com_k2/blog-list/item.php on line 228

with the source K2 template. right ?

I extracted the zip file github.com/getk2/k2/archive/master.zip and checking the folder structure.
Is this in components/com_k2/.......... inside ?

Appreciate your help

/components/com_k2/templates/default/item.php is the actual location.

Fotis, okey in Summary:

On the homepage is the warning:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/rapigukk/public_html/templates/bemax/html/com_k2/blog-list/item.php on line 228

This is the line 228 on item.php from my template (downloaded):
<?php if($this->item->params->get('itemExtraFields') && count($this->item->extra_fields)): ?>

and in the /components/com_k2/templates/default/item.php is:
<?php if($this->item->params->get('itemExtraFields') && isset($this->item->extra_fields) && count($this->item->extra_fields)): ?>

My questions:
Shall I change from master-template with this on my page ?

Thank you for your help
