Broken apps on demo yunohost instance

Hello.

I was looking through the documentation, and came across the demo yunohost instance.

It has a few broken applications installed. It would be wise to update this, so that people trying yunohost are able to experience what yunohost has to offer.

Piwigo is installed, which is a broken application.

Rainloop is a public archive.

strut… looks like it just broke recently? I’ll write that one off as bad luck.

Wallabag and tinytinyRSS would not let me log in with the username/password demo/demo .

I apologize if I have created this in the wrong place. This has to do with the documentation, and I consider this contribution, since I do not need support here.
