Hi,

I have this notice when i save Item or Category with Joomla 3.2.1 :

Notice: Undefined index: in /joomla/administrator/templates/isis/html/message.php on line 24

I found this post but I don't know how to apply the patch to solve issue.

Can somebody explain me how to do it ?

Thanks.

use this Link getk2.org/assets/get/ to get the development package from K2 as a zip.

Then install it just any other extension.
