Better Loot wont update on server

Everytime i change the loot tables using a website called lootify. ill put it back into the folder but nothing happens to the server, ive restarted the server. Says i shouldnt have to, but it wasnt working, do i need to wipe my server for the new loot tables to work? if not, what do i need to do?

this is what it gives me when i type o.reload BetterLoot

you don't have to restart the server but you do need to reload the plugin. this error means there is a problem with your lootttables.json file, check it over carefully make sure all fields are valid, or pastebin it and link
