Hello!

I have tested the feed, it looks like an issue with the Newsfeeds plugin. I am looking into it today.

Thanks for reporting the issue

Ok, I have found the problem:
the Atom parser only takes into account the updated date, not the published one. I based the code of the plugin on the published date.
I will make an update to the plugin soon to rectify this.

Even with the correction, I am afraid the Atom parser won't work for you:
- the URL of the link entries is incorrect (the Joomla parser uses the 'id' property as the link, which is strange),
- the content parsed is coming from the 'summary' property, which does not contain the image, therefore the feed can't be shown with images, since the parser does not return any.

Note that:
If the 'id' property was not a URL, the parser would then get the proper link.
If the 'summary' property was not present, a cleaned version of the 'content' property would be selected instead.

The Atom parser is rather limited in my opinion, if the feed was formatted as RSS 2.0 instead, it probably would be parsed in a better way.

All data is cleaned by the Joomla parsers so there is no chance of an 'attack'.

The problem was coming from the fact that I did not see that the Joomla Atom parser was not considering the published date if the updated date is present.

I have updated the code of the Newsfeeds plugin so it can't crash on an ignored published date.
