Sorry I had a condition!
Esp is ver 2.0.0
Yup… time to upgrade Prefered version is 2.4.0… if you can’t see it as an option in your IDE, then make sure you have this in your IDE preferances: File -> Preferances
http://arduino.esp8266.com/stable/package_esp8266com_index.json
Then go back into the boards manager and update.
