K2 » Item edit form opens an error page

Hello,

I created a menu item linked to K2 > Item edit form to allow users to submit contents from the frontend. I have enabled "frontend editing" on the K2 configuration. While logged in the frontend, I clicked on the link I created to create K2 contents, I got this error message:

Oops, you've encountered an error
It appears the page you were looking for doesn't exist. Sorry about that.

What do I need to edit to make it work?

Thanks!

Basically you did not setup properly.

1. K2 User needs to be in K2 User groups
2. K2 User groups needs permission to add to K2 category you selected.

So go to K2 usergroups and give them permission to add to category.
Then go to K2 users and add them to the Group.

See you around...

I made a new quickstart installation and the error is resolved. Thanks.
K2 new language install causes the error. When i installed a new K2 language... error return.

Then there must be something wrong with language files. Extract the package and replace content of each K2 Language file with English content to make find which file is causing the problem.

Or Alternativelly let me know which pack and from which link you have downloaded this language pack and I ll check it on my server.

See you around...
