I'm trying to include the default RSS widget provided by WordPress. In the URL adress, I typed http://www.singabuzz.sg/feed/ (www.singabuzz.sg is the url of the blog) but it doesn't worh and gives an error (A feed could not be found at http://www.singabuzz.sg/feed/. A feed with an invalid mime type may fall victim to this error, or SimplePie was unable to auto-discover it.. Use force_feed() if you are certain this URL is a real feed.) when displayed on the website. I have to precise that the blog is under construction, not yet opened to public and accessible only by username/password.
Thanks for your help.
