Whenever I try to start my server it works fine at first. However, in a few minutes it stops it self with this error: https://pastebin.com/HZ8cFN9v What can I do to fix this? It is not the Image-On-Map plugin, I removed it and it still doesn't work. EDIT: The server even breaks without any plugins. EDIT 2: After trying again with a new world, I found out it has to do with the world, not the plugins.
