RSS issue

Hi,

I am trying to set-up a simple RSS wdget on my WordPress site… i have a similar site and the URL for the feed works fine. It used to work on my troublesome site but now I cannot re-add it…when I do and try to save it it just looks like it is saving but the timer goes on and on. I know the feed is valid as I have tested and it works on my other site. I have removed and readded the widget with no joy. Perhaps there is a simple RSS plugin to use – however would prefer to use the one present in Widgets if possible.

Feed is: http://feeds.news.com.au/public/rss/2.0/fs_breaking_news_13.xml

A same of the RSS feed working is via: http://sydneyscorpions.com

Many thanks in advance.,
