World won't generate

Whenever I try to start my server, it crashes and says to check the logs. When I go to the logs, it says that it has failed to generate the world. I've tried going into the world generation option in the side bar (separate from the logs) and nothing I've done has helped. I'm not really even sure where to look or how to go about resolving the issue past that, any help is appreciated! The server has never been opened before, so the world hasn't been previously generated either.
