So this is what happend. I was working at my server spawn and then I was going to make a place for ships. So I was going to World edit some water there which was a lot more then I thought world edited (20,000 blocks) and then my server crashed. I restarted the server up and then I could talk but i spawned in the sky and I was falling into the void and then my minecraft crashed. I tried force updating. I tried restarting my server some more. Nothing worked.. I cant use commands even thought I'm the owner.. And all my other players can still get on, but when I get on I just fall through this sky and below this weird ocean into the void and then I crash.
