Problem with Upnp Bridge.

Hello
I have installed Logitech Media Server Version: 7.9.1 - 1498468656 on Ubuntu Server 16.04.2 LTS.
I added the plugin UPnP / DLNA bridge but I have this error:
"Configuration file missing - create one by clicking" generate "or, if autosave is on, refresh this page"
The problem is that I do not have the "generate" button.

I checked: "Start the Bridge" but it is: "Not Running".

I have the following error in the LMS log:
"[17-06-27 13: 26: 23.1353] Plugins :: UPnPBridge :: Squeeze2upnp :: start (92) no binary set"

I went through the forum but I could not find a solution.
I restart many time, re-install also but nothing seems to work
Can you help me please?

Thank you
Yannick
