Hello Vladislav,

Please enable error reporting and set it to development from your site's global configuration.
This will print the exact error. Once you have this please paste it here.

error output - proffesionalnyj for php developers. No specific errors .
Just Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Backup.
Then try the DEV version of K2.
Let me know if that solves your issue.

You can get it from here: getk2.org/assets/get/
