Be sure to check:

DB tables (and repair them)
Paths to /log and /tmp files
File and folder permissions and also if the files belong to the correct user/group

Thank you for respond but I have check all again and didn't find nothing.
I am really in a bad position right now. I need solution fast for this problem. On old server we had many other errors mainly be cos wrong php or apache version and suhosin but k2 was working ok. Here is all working but k2 categories don't work.

I have no idea what I am missing here.

Have you set error reporting of Joomla Global Configuration?
If no, please set it to maximum or development and let me know what is the error.

Only if I set development erros to show it give me errors an all pages:

But dos have any of this any to do with K2?

These are not errors, and not releveant to K2.

Try to disable any plugins and modules to determine which is the reason for this problem.

I would recommend disabling the oserouter extension as a start.

Nothing work. I am so despert that I can't fix this. Is it posible that is something with Jomfish component.

Thank you for all your sugestions for now.

We have found the solution.
Problem was due low memory limit in PHP configuration. As we are on shared hosting and our host did not want to increase the limit we do it with php.ini file as they suggested.

Thank you all for your help and I hope that this solution will help someone else to.
