Which version of flash-socket/python-engine to use for Webserver?

[caporalfourrier]

I am getting the following issue when I open the webserver:

The client is using an unsupported version of the Socket.IO or Engine.IO protocols (further occurrences of this error will be logged with level INFO)

I can open the google maps page but I see no planes even though I am continuously receiving data. No issues with ZMQ either. I tried downgrading to a few different older versions but it didn't work and now the webserver.py itself won't run. So what version should I use?

I'm encountering the same error and the same issue with the map not showing planes despite receiving data. Have you worked out a fix for this? @caporalfourrier
Perhaps @mhostetter can provide some insight.
