RSS App bug with XML file

Enonic version: 7.5.0
OS: Ubuntu

I did every step at the setup guide at:
But for some reason the page of the rss-page content shows the following string “This XML file does not appear to have any style information associated with it. The document tree is shown below.”.

If I take a look at the Log Browser app, I see a log info from the rss app showing the object with two properties, feed and items. The items is an array filled with the information that it’s supposed to be printed in the XML, but it’s not showing that in the XML file.
Do you know what should I do to solve that?

We have released a new version (1.0.2) of RSS app. Can you install it and see if it solves the problem?

It seems to be working fine, tks ;]
