if you are upgrading from 2.4.0 of babble self hosted, you will need to do the following steps:
- download a new babble.js and packages.json from ACP->Babble->Configuration->General, Node Settings tab.
- replace your babble.js and packages.json with the ones you just downloaded.
run from terminal/ssh in the directory that contains the babble.js and packages.json
(if the above command throws an error, try npm rebuild and then run npm update).
restart/start the babble.js
this is needed cause of updates to babble.js and upgrading socket.io from 1.4.5 to 2.0.3.
