On 10/10/2012, Twitter stopped serving Atom & RSS feeds using ye olde style URLs:

• http://twitter.com/statuses/user_timeline/{USERNAME}.atom
• http://twitter.com/statuses/user_timeline/{USERNAME}.rss

Since they are returning an HTTP 404 (not found) status code, which provides no information to Awasu on how to automatically update your Channels, these feeds will display the red X error icon, and you'll need to manually update your Channels to use the new-style URLs.

The new style Twitter feed URLs are:

• http://api.twitter.com/1/statuses/user_timeline.atom?screen_name={USERNAME}
• http://api.twitter.com/1/statuses/user_timeline.rss?screen_name={USERNAME}

If Twitter had of properly returned an HTTP 301 (Moved Permanently) status code Awasu would have updated our Channels automatically , but I guess that's too much to ask from Twitter.

Thanks for the update. I'll try get the wiki and all the various Awasu extensions updated shortly.
