My chat is not showing up at all in my game?

I have a massive problem with my chat, no matter what it's not showing up in-game or in-studio.

Here is a gif of what is happening: https://gyazo.com/1396bb6021c0e7861aa0757aacccb9ba

(Sorry for link to GIF it's cause idk how to post pictures/gifs without links)

I have fixed it, somehow me putting my "Welcome" chat message in the StarterPlayerScripts made the chat break
