Hi, ohh,,, this is first time I see such a error.
1) Could you send me access to back-end I will check Joomla settings, probably this is "small" bug.
2) Did you have any errors messages during Joomla installation ? Or red marks on test page ?

Sendt in PM.

Installation run without any problems/error.

Yes, I saw - whole error message is "1054 - Unknown column 'state' in 'where clause' SQL=SELECT created FROM dansk_k2_items WHERE state = 1 ORDER BY created DESC LIMIT 1;"

I had to disable 'Show last update date" in template settings. Now is working.
