Hello!

I'm working on a website with Joomla 3.3.6 / k2 K2 v2.6.9 and K2 modules me the following error message:

I have reinstalled K2 and still appears.

Any ideas?

Which other extensions are you using?

The other extensions I use are:

- Jom Estate
- Mijo SEF (With Plugin K2)
- Akeeba Backup
- Akeeba Admin Tools
- Falang
- JCE Editor
- RSForm
- Simple Image Gallery Pro
- K2 Multiimages (Plugin)
- Nonumber - Advanced Modules (Admin)
- Nonumber - Sourcerer (Admin)

I have another project just like with K2 and these extensions and working properly ...

Any ideas?
Thank You!

Try deactivating all K2 related extensions one by one to see which is causing this issue.

I disabled the three related extensions K2:

K2 - Simple Image Gallery Pro
System - K2MultiImages
Search - K2 - Falang

Still not working ... :(

This error coming from an extension which is not compatible with K2 or an outdated extension.

If you are seeing this in the frontend then you need to make sure that your template supports the latest version of K2.

Hello again,

I think the problem is with the extension of Jom Estate, I have written to developers, and tell me it's a problem of K2.

How can we fix it?

Hello, since all of K2's modules work fine out of the box it is a matter of other extensions to ensure compatibility with K2.
