Errors after Update to PHP8 was created by Hermann
Hi, we get the following error messages when calling up a K2 category link.
Runs under Joomla 3.10.11 with PHP 8.0.24 and K2 2.10.3.
Strangely enough, the module works, but not the direct link to a category.
No HTML overrides.

Here the debug-Info... any idea?

Regards
Hermann

I am sorry to offer without checking properly your question.
Not only K2 also Joomla's it self gives error too.

It might happen because of PHP version.
Can you update it to 8.1.0 or 8.1.11 and try again?

Can you create "test" folder and upload fresh joomla and than install k2 dev version on it?
Than try it if it gives still error or not.

Here are links for you
downloads.joomla.org/cms/joomla3/3-10-11/Joomla_3-10-11-Stable-Full_Package.zip?format=zip
getk2.org/downloads/?f=dev

Test it before and after k2 installation

Hi, there is also an error in the backend, even there you can no longer access the categories.
Runs under Joomla 3.10.11 with PHP 8.1.11 and K2 v2.11.0 [Build 20220701]
Call to administrator/index.php?option=com_k2&view=categories shows error:

Same issue here - after upgrading to PHP8.

0 Serialization of 'Closure' is not allowed
Call stack
# Function - Location
1 () - JROOT/libraries/src/Cache/Controller/:188
2 serialize() - JROOT/libraries/src/Cache/Controller/:188
3 Joomla\CMS\Cache\Controller\CallbackController->get() - JROOT/libraries/src/Cache/Controller/:45
4 Joomla\CMS\Cache\Controller\CallbackController->call() - JROOT/components/com_k2/views/itemlist/:691

But it occurs only when Joomla Debug is enabled.

*Extra info: 
I got the above on the localhost dev site.
Once I tried the same on an online dev - Joomla returns this: 

Something on your site is broken and tries to save the plugin state in the cache. This is a major security issue and will cause your site to not work properly. Go to your site's backend, Global Configuration and set Caching to OFF as a temporary solution. Possible causes: older versions of JoomlaShine templates, JomSocial, BetterPreview and other third party Joomla! extensions.

First off, I doubt the message you got on the live site comes from Joomla, it must be some security plugin or service.

Secondly, the previous poster's issue was a third-party plugin (incptvk2multiplecategories), not K2.

I'm guessing the issue is probably similar with your site as well. You need to double check your system plugins as that plugin type can execute automatically anywhere in Joomla.
