The site has now been redesigned. The typo is gone.

You can now test RSS feeds using the preview button. You should no longer get an error on download. If you have a valid RSS feed and are still having issues, post a link to the feed and we can work out if there is a bug. The most common RSS bug we run into is site authors adding additional, unexpected fields to the RSS feed.

These were common issues with the old code base. Hopefully both of these issues should now be fixed.

This is sadly harder than you might think As a compromise we have now enabled the users to preview their data sources. But have no plans to produce a full preview.

This is caused because I have linked some statistics data with your app and the delete method is unable to delete it. This bug is now logged and a fix should be a pplied in the next update.

Taking a look into this now.

No you're not doing anything wrong... Your system doesn't seem to be able to locate a WinJS file. Are you able to build Windows 8 apps using JavaScript on your machine? E.g. File > New > Project Windows Store JavaScript project.

This should now be fixed

So we started with HTML5 and JavaScript... We wanted to support phone but it's not currently possible to dev Windows phone apps in JS in the same way so we were forced to use C#. There are no plans to build a Windows 8 C~ version at the moment.

New Version of ZipApp went live an hour ago.. I should fix this issue.
