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?

Install K2 v2.9.1 (dev) on top of 2.9.0 from: github.com/getk2/k2/archive/master.zip

This should resolve the countable() warnings in PHP 7.2+.

The error "Using $this when not in object context" which probably causes a fatal error in the frontend may come from a 3rd party extension that utilizes K2 content.

A URL to your site(s) would also help.

Have applied the latest 2.9.1 dev, still got the following error

Warning: count(): Parameter must be an array or an object that implements Countable in /home/xxx/public_html/site/templates/xxx/html/com_k2/blog-2columns/item.php on line 105

Hi,

I'm getting multiple K2 errors since upgrading to php 7.3.0 across various plug ins and component pages:

Hello,

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
After installing current github version 2.9.1, I found the error on displaying K2 single item

( ! ) Warning: count(): Parameter must be an array or an object that implements Countable in C:\wamp64\www\jd_miami\templates\jd_miami\html\com_k2\templates\default\item.php on line 291

As the line 291 and 292 are:
<!-- Plugins: AfterDisplayContent -->
<?php echo $this->item->event->AfterDisplayContent; ?>

I am stuck.
Could you investigate this problem?

I get this error on opening a new article:

Warning: sizeof(): Parameter must be an array or an object that implements Countable in administrator/components/com_k2/views/item/view.html.php on line 338

It addresses the extra field section of the view.html.php:


Line 338 is:

Any idea? :-)

We don't implement that class ("Countable") in our code. It probably comes from a 3rd party extension that integrates/extends K2 content. Look at your Plugin Manager first.

Hi,

after upgrading to the newest K2 version every article starts with:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/.sites/43/site4952321/web/components/com_k2/models/item.php on line 76

and ends with:
Warning: count(): Parameter must be an array or an object that implements Countable in /home/.sites/43/site4952321/web/components/com_k2/templates/default/item.php on line 248

Joomla 3.8.12
MySQLi 5.5.59
PHP 7.2.10

Any ideas? - Thanks

Hello there,

So I have a fresh install Joomla Version 3.8.5
Just installed K2 and started to set stuff up.

Whenever Joomla brings up a K2 Article Page I receive the 2 error messages: The first one (1) is on top of the screen before the title, the second message (2) before Read xx times.

1) Warning: count(): Parameter must be an array or an object that implements Countable in E:\xampp\htdocs\Joomla\components\com_k2\models\item.php on line 877

2) Warning: count(): Parameter must be an array or an object that implements Countable in E:\xampp\htdocs\Joomla\components\com_k2\templates\default\item.php on line 248

I receive no other error message anywhere on the site. Everything else is normal. I went through the count options on the category screen and turn off anything that was counting related. Still no go.
