I double checked my JSON with http://jsonlint.com/ before uploading the config file. Everything is valid. However I'm getting this message.

Plugin was outdated. Sorry for the spam.

The issue is PlayerDatabase. You got to remove any references of EBS from the PlayerDatabase data file or wherever you have it saving too

Yea, I didn't have to do that. All i had to do was update the plugin to the newest version. I was working on this plugin, and downloaded all the plugins at like lets say 8pm, and you pushed an update at around 10pm or something two hours later, and i was still working with the old plugin. I didn't have to do anything at all besides updating the plugin. But thank you very much for the reply! :D
