JSON - Exception in server tick loop

If you find your server not starting up with the following error: java.lang.NullPointerException: Exception in server tick loop at net.minecraft.server.v1_7_R3.JsonList.load(JsonList.java:171)

This means there is an issue with one of your ops.json/whitelist.json files.

To fix this, do the following:

1. Stop your server

2. Access your servers files using FTP and delete the ops.json, whitelist.json and usercache.json files

3. Start your server
