I'm new to modded servers. I use RCON.IO

When I click the Chat tab at the top, the dialog is completely blank.

I do not use BetterChat or RustAdmin.  Any ideas how to get basic chat to reappear in RCON?

does it use chat.tail ? because thats broken again. it worked before? you should contact them about it. They don't even use https?? I'd find something different.
