Error when starting daemon

[progof]

Hello,

Compiled the coin code on VDS and launched the daemon and this error appeared:

2018-Apr-15 18:05:28.217926 ERROR   Failed to init: genesis block mismatch. Probably you set --testnet flag with data dir with non-test blockchain or another network.
2018-Apr-15 18:05:28.218066 ERROR   Failed to initialize blockchain storage
2018-Apr-15 18:05:28.218184 ERROR   Failed to initialize core

The message indicates that the genesis block is different than the one stored on disk. Try remove contents of the datadir, by default, it is ~/.bitcoin, and try again.
