Do you have any K2 related extensions installed?

I have only simple image gallery pro plugin and k2 import. Al the plugins modules components of k2store are disabled

Any news guys about this problem?
i have the same error saving/modifing an item by forntend k2 panel.
Using Joomla 2.5.7 & K2.6.1.

I'm also experiencing the same problem. Save / Edit items in front end containing Extra Fields fails with Fatal Error.

See screengrab :- screencast.com/t/rss3jp2pgc

J 2.5.8, K2 2.6.1

Shaper Simplicity II template

Also had RT Afterburner template + Rokbooster plugin. Uninstalled both.

Hi. This issue has already been resolved. You can wait for K2 2.6.2 or use the SVN version at getk2.org/assets/svn/

Была тоже такая проблема при сохранении материалов c фронтенда К2 2.6.1
Обновил до 2.6.2 SVN version проблема решилась но появилась другая.

У меня есть дополнительное поле URl,
Когда в него вношу данные и сохраняю - результат A и r.

There was also a problem when saving materials c frontend K2 2.6.1,
Updated to 2.6.2 SVN version problem resolved but there was another.
I have an extra field URl,When am making it, and save - the result of A and r.

Hi, same issue here.
I used the SVN version, and the first error ( Fatal error: Call to a member function getSearchValue() on a non-object in /home3/davizxtr/public_html/administrator/components/com_k2/models/item.php on line 721
) has gone.
But now the attached file appears
The items was saved correctly
Thanks

Issue has been fixed for the next release.

@Alejandro
Ensure that user is assigned to a K2 user group with the appropriate permissions.

Hi Lefteris,
Thanks for answer
I think the user groups are fine. In the last version i didn,t have this problem with the same users.
See the attachment, please

Ok. Changing this (see attachment) it works fine.
But my intention is that users can create their articles in the frontend, but not publish nor edite them after the articles was published by an administrator.
Can i do this?
Thank you
