Even wiped everything and did a fresh install with no modifications at all. As soon as the plugin loads up, no chat is displayed in game. No errors in the logs, plugin loads and unloads fine.

 I finally figured it out.

For the default section in the data file for the default user profile I had to change these.

"Text": "[default]",
"Color": "#ae1ae8",

"Chat": "{Title} {Username}: {Message}",
"Console": "{Title} {Username}: {Message}"

To this:

"Text": "",
"Color": "",

"Chat": "{Username}: {Message}",
"Console": "{Username}: {Message}"
