An error occurred saving config.

[snapet]

Hi, not sure if this is a bug or not, so decided to drop this here first.
I have my Dashy on a Turnkey Nodejs LXC container on Proxmox.

When I try to save to disk after editing in the GUI, I get: "An error occurred saving config."
Checking in web developer tools I see the following error:

XML Parsing Error: not well-formed
Location: http://10.200.11.33:4000/config-manager/save
Line Number 1, Column 1:

I have tried changing permissions on conf.yml but that doesn't seem to be the issue. When I drop the link in a browser I get a 404. Editing the yaml files and rebuilding does work but I'd really like to get the GUI editor functional.

Can someone point me in the right direction or is this a bug after all?

Thanks for Dashy and any help!
