Server Error, no mods installed | SpongeForge

[Craze250]

[14:37:17] [Server thread/WARN] [minecraft/Chunk]: Could not set level chunk heightmap, array length is 0 instead of 256 [14:37:17] [Server thread/ERROR] [minecraft/MinecraftServer]: Encountered an unexpected exception java.lang.IllegalArgumentException: ChunkNibbleArrays should be 2048 bytes not: 0

This is my error before the server shuts down, anyone know how I can fix it?

Hi there,

I suggest resetting the world by going to "File Manager" and deleting the folders "world", "world_nether" and "world_the_end" (when the server isn't online) and try to start up the server.

If this didn't help, contact support here then click on "Contact Support" on that page and explain the issue.
