can someone please tell me the correct settings for yiimp. I am getting all blocks rejected on my private pool.

I don't know if must be checked or not:

- Has submitblock = Checked or Unchecked
- Txmessage = Checked or Unchecked
- Masternodes = Checked or Unchecked
- RPC Type: POW or POS?

I tried all combinations nothing seems to work for me.
