Do you know if you are able to send the server logs instead of the crash report. Once you get the server logs, go to https://pastebin.com/ and paste it there. Then click create paste and either send the link back in here or to me in Discord. Tarna256#8675. The server logs could help more. If you don't know how to access logs, here is a tutorial.

Thanks, Me

It seems like there is something wrong with the json files on your server. Delete all the json files in the file manager then restart server. The json files should be 
banned-ips.json
banned-players.json
ops.josn
whitelist.json

There might be one or two more but im not sure. Delete the json files and restart the server and it should get fixed.

ok Thanks!
