I just did a Fantastico install of 2.0.5 and when I go to:
http://www.thesandiegobeat.com/feed/ [I have customized the permalinks - but that isn't the problem, since I tried with it off and same thing] in a browser, it shows a blank screen.
If I go to FireFox and do a "live bookmark" it works. If I open the properties of the live bookmark and paste the URL into a browser, it shows xml, as it should. If I refresh the xml is gone.
This seems wacky...any ideas?
