Creating and running a Rohan server requires you to have extensive technical skills in programming and computer technology.
Read the error messages. They are telling you what the problem is (hint - it has to do with missing stored procedures).
If you have the technical knowledge to understand what the errors are saying then you can fix it.
Do you understand what stored procedures are and how to create them? If not, I strongly advise you to delete the Rohan server you are trying to create and gain the necessary technical schooling.
