Tmux not starting after an upgrade

Recently upgraded my version of Tmux and after could no longer start a session. After banging my head on tmux’s config files it turned out that sessions that were currently in play were the problem.

So if you find yourself in this situation… make sure to stop all sessions and most likely you’ll have Tmux working again.

An easy way to kill everything would be tmux kill-server.
