I hope so; Joomla 3 support ends in August.

K2 is not yet ready for J4. Our plan is to release an update within the first half of 2023.

Same issue here
Jim

I want to upgrade from Joomla 3.10 to Joomla 4.26. However, the pre-update check gives me two errors. It says there is a potential upgrade issue with two K2 plugins:

System - K2
User - K2

How can I rectify this? Please help. 

there is error in k2.11 after upgrade to php8.0When I hit publish or unpublish button in k2 content
error : Attempt to assign property "id" on null
please review and help me to fix it

Hello.

after the last K2 upgrade, the following error appears:
0 count(): Argument #1 ($value) must be of type Countable|array, null given
/home/.../public_html/plugins/system/lscache/components/com_k2 . php:46

The error is only when saving and closing an article written in k2 or when clicking the close button.
When disabling the Litespeed plugin, the error disappears.

Last K2, Jomla 3, Litespeed plugin

What can be done?

This error comes from a K2 override or other Joomla module or plugin.

Open the Joomla debugger and switch error reporting to maximum to identify the exact origin of the error.

Hi, I update K2 installing the file downloaded from getk2.org/downloads/?f=K2_Rolling_Release.zip
but nothing change, in the blog page appear this error:

0 - count(): Argument #1 ($value) must be of type Countable|array, null given

@Gee
The joy in developing K2 was never lost :)

And of course it's natural that Joomla evolves, but they way it's done every freaking time has become annoying when life gets in the way (inevitably). As we grow older, we prioritise differently. Practical is better that shiny/new.

Joomla 4 brings nothing new to the table for end-users. As did Joomla 3 over 2.5. The only major feature for end-users came after Joomla 1.5 with the advent of custom user groups/ACL. That was it and still is. (And as for PHP compatibility? Joomla 3 & K2 work *just fine* in PHP 8.1. See the updated not on the initial post in this thread...)

Joomla is a platform like an OS. And like any serious OS it should limit its features to core & improve on them. As a good example in open source, see how Linux OSs evolve over time and how the top GUIs like KDE & Gnome limit their offered software to core/essential or small helpful utilities. If any of these attempted to create a LibreOffice or GIMP or Blender clone though, would be instantly mocked at by the community...

But no, the usual Joomla devs/fanboys/co-founders that control the project, who actually ousted any other reasonable people in the project or community over time (because the latter obviously had more important things to deal with in life), think Joomla has a holly mission of providing everything for 99,9% of sites without any 3rd party extensions, while following every moronic programming pattern or trend they can so as not to be called old or obsolete in programming. Joomla *used* to be at the forefront of CMS software. Now it's just copying what others are doing and it's also doing so in bad way. They mock WordPress which controls half the goddamn internet (because it's practical & backwards compatible), yet don't grasp why Joomla's percentage is dropping or why end-users don't get their genius.

This is a) sort-sighted (no understanding of the original software's success = it's community of 3rd party devs) b) reveals character complex (personal egos and such) and c) it's just plain stupid from a business standpoint. These people usually have no real-world/professional experience and I'm not talking about selling extensions as a professional endeavour, I mean actually using Joomla to deliver projects (sites or web apps) for paying customers/businesses.

You know what end-users and businesses say for J4? It's actually sh*t. And they have no damn reason to change to it, especially when the core software they utilize (which 100% covers their content needs) is up to date, modern looking, fast loading and continuously upgraded with meaningful features.

Everything else is hypothetical developer joy. It usually takes all the hardcore-OOP/new/shiny/whatever fans in Joomla a couple of years to realize after each major b/c-breaking release, but when they do, they have already "shot their feet". And the circle continues by breaking the b/c one more freaking time with the next "big release".

Which is why K2 will gradually switch to the simplest humanly possible MVC structure ever, without sacrificing its extensible nature or features. And yes, you might see K2 in WordPress at some point in the near future...

K2 v2.11 has been released.

See: getk2.org/blog/k2-v2-11-rolling-releases-joomla-4-and-more

Hi, 
I get an error message now when saving items and catgegories due to the upgrade of PHP to 8.0 and i read that installing K2 2.11 would solve the problem.
I have installed 2.10.4 for there was a thread saying that might work but it didn't help. I have some custom css but when I deleted that I still got the error message when saving an item.

I can find version 2.11 on Github but do I need to replace everything file by file? Or is there a quicker way?? It stated somewhere that you can get a zip file??

Thanks for helping

Hi everybody,

My pages by tags from file tag.php display the following error when I try to upgrade my php version from 7.4 to 8.0 :

Non-static method K2ModelItem::getItemTags() cannot be called statically

For information I am using k2 v2.9.0 which I cannot update at the moment due to bugs on later versions.

Maybe some could help me ??

Thanks a lot...

Hello,

I can't upgrade my site to version 8 of PHP.

This error is displayed in "development" debugging on my site (php 7.4) :

Warning: count(): Parameter must be an array or an object that implements Countable in /homepages/--/---/htdocs/---/templates/ts_news247/html/com_k2/templates/default/item.php on line 311

Could this error be the cause? Do you have a solution ? Thanks

Regards

I'm having a similar issue (I think) where my SEM Rush audit is coming back with all sorts of different URL's for my category pages:


It's a K2 + SH404sef site that has been migrated / upgraded from Joomla 2.5.x so I'm hesitant to start flipping switches.  

It might even be because I was using an outdated version of the K2 -> SH404sef plugin for a while.  I think that's all current now, too.  

Can you point me in the right direction? 

Thanks!

Is K2 up to date as well?

I would also advice using the Joomla Update component to re-install Joomla entirely, not just the upgrade patch you most likely did before.

An update on the matter.

It has come to my attention that Plesk, the hosting control panel, will block the CSS/JS files of older elFinder releases. elFinder is the 3rd party media manager that is bundled with K2 (and SIGPro etc.).

This is probably the reason why you see a blank page (if it's not a JSON issue of course as I indicated above).

Please confirm that your site is hosted on Plesk for those with this issue.

I will upgrade elFinder in its latest release in a while and I'll update this thread in the coming hours (or sooner) so you can install the 'dev' release of K2.

Thanks @fotis and @Daniele.
So I can upgrade K2 with that release.

@daniele, put on the other hand, what do I need to do to get YTP to use K2 as a content source?

Hi. I have also a big site with K2 + SIG pro to upgrade to Joomla 4, and I'm waiting for news ...

I found this, which I am going to try on a J4 upgrade running on a staging site. This is one of only two dependencies left.

geekflare.com/export-k2-items-to-joomla-articles/

EDIT (Didn't work on a 3.10.5 site - I'm going to export a couple tables, match them up to com content tables, and import the new rows that way)

Hi,

In the past, www.blackfire.io/ helped me to diagnose performance issues. Also, Xdebug has a tool to check performance issues.

This is my leading case, running K2 and Joomla 3: sisanjuan.gob.ar/. Yesterday, I upgraded it to PHP 8 and it is delivering pages in 100ms.

Best Regards
