Cannot Post in Chat, Template Output Breaks.

I've tried this with both chrome roll20 and firefox roll20, I log in, go to my game and everything looks fine. People have outputted 4e powers (the sheet template no api here) and its fine. But I go to type something and press enter, and not only does nothing show up but then I get this weird glitch. I have NO idea what is going on. EDIT: Cleared chat archive. SEEMS to have fixed it. For now.

It is a corrupted roll template or something of that nature and the usual procedure is the clear the chat archive from outside the game (not from inside the game). If there is info that needs to be saved, it is recommended that the creator of the game saves the archive log before clearing it.

Ok well I cleared it and my players are saying they're getting issues again.

As Pat said, a game's Creator is often able to fix issues with their Text Chat by Clearing the game's Chat Archive from the Settings dropdown on the Game Details page of their game (note: not Clearing your Current Chat Log from the My Settings tab of the in-game Sidebar). Try clearing the Chat Archive again and ask your players to try again.

Clearing works until someone triggers the corrupted/bad template again, so clear the chat archive then carefully activate macros one by one until you find the misbehaving one and then fix it :)
