Error while editing and saving a page.

[Peter Franca]

Hi all, 
I am having this error when I try to save any modified page.

I have checked if my reverse proxy has the Websocket enabled/installed and it has.

I am wondering if I need to do any special configuration on the reverse proxy after having this feature enabled.

What proxy are you using and how is Synchrony configured in it?

I've only ever used Synchrony behind an Apache Proxy and I know that needs a few extra lines to make it work, which I can drop over, but I don't think they're much use if you're on nginx or lighttpd etc
