Alt coin client returning error: {"code":-32601,"message":"Method not found"}

[cryptodruti]

I've spent the weekend cloning alt coins for shits n' gigs, and was able to successfully clone a scrypt coin, and a few other simple coins. I decided to step it up today and tried cloning a PoW/PoS x13 coin, basically the same process and was able to get past mining the genesis block and connecting two nodes. However the client only accepts certain commands such as "getinfo", "getnewaddress" and a few others, but returns the error: {"code":-32601,"message":"Method not found"} for the command "setgenerate true" and a few other commands. Anyone have any idea whats causing this? I would really appreciate some help

It's not much of an insight but "method not found" errors are automatically or programmatically generated responses because it doesn't know the commands you gave it.  I noticed you said "a scrypt coin" which omits which code base you used.  Code bases can claim to be "scrypt coin"s but not implement all functions in other scrypt coins which is probably what you're running in to.
