Same result for me.

The truth is I have tested it with multiple of 2.5.11 sites and all updated without a hassle so I wiil need some more information on your setup since I will try to reproduce the error.

Which version of PHP are you using?
What other extensions are you using?
Is your site native 2.5.x or it started as a 1.7.x?

Sorry for sounding a bit like a Gestapo Officer but I want to reproduce the error.

Regards.

Dear all, hello. I confirm the exact same error too. Joomla 2.5.11 with K2 2.6.7 (fresh install). I know 3 partners who have the exact same problem and there are several forums other than K2, where people are looking for a solution. I have found only this, but it doesn't work:

"This issue is from K2.
Please go through \administrator\components\com_k2\models.
Rename the userGroup.xml -> usergroup.xml

If you have any other question please let me know."

Please is there a fix for this?

Edit/Update:

I tried installing a fresh copy and update through Joomla extensions update and I have the exact same result on 3 different websites. I only see this error on new/edit item and new/edit category on the backend.

Hi, NO! it is not working... i still have this strange error ( attached ) // error is in polish lang
do you have any other sugestion ?

Dear cegi, please read my post correctly. I didn't suggest a solution. I simply pointed out that whatever I do, it is NOT WORKING.

Why isn't anybody from K2 team answering? This is a problem that trully exists.

Hello,
I'm experiencing the same issue,
after upgrading from 2.6.6 to 2.6.7 i get "error 500 could not load xml file"..

I get this error when I try to create/modify a k2 item (frontend/backend)
I can confirm it occurs only after upgrading to 2.6.6 to 2.6.7
I could reproduce this exact behaviour on my test server and on my localhost (windows/xampp)

I reproduced it with last two joomla versions (2.5.13 - 2.5.14).

It seems not to be related to any server misconfiguration.

Any advice before updating on my production site would be gladly appreciated : )

I also have the same error on a Joomla 2.5.11 site. A Joomla 3.1.5 site following the K2 upgrade worked fine.
On the 2.5.11 site I re-installed K2 in the Extension Manager but still have the error.

Same error - new site running Joomla 2.5.14 just installed K2 2.6.7

Have researched many different possible solutions, none of them having any impact - The usergroup.xml file is already named correctly, so no need to change it.

Thought K2 might be a good solution for a project I'm working on, guess I found the answer I was looking for...
