The following error is thrown when rendering an RSS Widget or Media Widget in Flash View Mode using Strategy Web:

File not found. Make sure that the URL is valid and that the ‘Use Proxy’ setting is checked if the URL is on a different domain than Strategy Web.

File not found
The RSS Widget or Media Widget cannot communicate with the website that hosts the data Feed.
Verify that the URL pointing to the data feed can be reached by typing the URL directly under the browser. If it is, there may be two options for the widget to access that content:

If the webserver hosting the RSS or media data content includes a crossdomain.xml policy file granting the Web client permission to access such content, the widget should render properly.
2. If the above is not an option follow these steps:
<allow-domains> <domain>news.google.com</domain>
</allow-domains>
