These are debugging tips gained from experience:

• If user is having trouble connecting to a client, make sure related shell executables are on $PATH e.g. #1640. A user's shell/terminal $PATH can be different than the one LightTable sees e.g. #1623. This is determined by js.process.env.PATH in proc.cljs.

• If you're having trouble connecting to a Clojure(Script) project, check this troubleshooting list.

• If you're having trouble connecting to the Clojure Instarepl, you might have an old version of the Ultra Leiningen plugin installed. Check your plugins in ~/.lein/profiles.clj and make sure you have at least version 0.2.1. If this isn't the case, please open an issue, and we'll troubleshoot further.
