Today I played on my new server for around 2 hours. After I backed up, saved, I logged off... In like 5ish hours, I joined again only to be spawned in the same server, different world. The world completely reset, I didn't even have OP and the village where it used to be was GONE. Naturally I used backup, and it randomly told me to whitelist myself. So I did and joined. Same thing happened, the world completely reset. I did this 3 times!

There aren't other logs? I'm confused because this is the error message/only message when I try to start the server. The server just crashes I guess

Thats the only errors, those 2 lines

The error in the console is shown in the picture below! Help me for a cookie
