New version broken, 500 error

We just updated to the newer version and now cannot access no page in akaunting. All url's return a 500 status, what to do?

v.2.1.10 that is btw

You can enable debug to see the errors

Thanks Ahmet, this helps closing in to the error. I now see that there is an error while accessing the table "akvn_documents" which doesnt exist in the database! I wonder if this should have been created during the upgrade process, and what does the table look for, maybe i can create it manually...
