For quite some time now, I've been using SunriseXP to read the Onion's AV Club at http://www.avclub.com. Lately, I haven't been able to get it to work-- only a few bytes transfer as a blank page. The address is still valid. Any ideas?

Can't really help other than to confirm that I get the same result. If you try the RSS feed, you get the same kind of thing: just the entry page, then all of the links result in blank pages. Very strange.
