Hello,

Having regenerated all the files of configs in view of the new update because it did not really work anymore, I have a rather odd error on the bungeecord side, I have the latest version of waterfall in 1.14.4 and the latest version paperspigot in 1.14.4 as well as the latest version of the plugin.

Error: https://pastebin.com/smeWKfLh
Config: https://pastebin.com/tSVxtydQ

I also have this error on the paper servers: https://pastebin.com/UTsCLhhz

Bungee config line 87, there is a space between UUID_Type and the : char that should not be there.

Your MySQL user does not have the "REFERENCES" privilege, please add it.

Actually for the bungee error this is fixed and it seems that you have left a default space in the config file.
As for the errors for the database, I'm going to look at it, I'll let you know.
