Sky Factory 4 commands not working

1st Official Post

    I started a Sky Factory 4 server, but some of the commands aren't working. Simple commands like /help don't even work in the console. I am an OP and I can use /gamemode commands in game but no other commands. Please help. Thanks.

    Here is the log if it is useful to anyone:
