Well, not quite, but at least the site finally updated again.
Do I know why? No.
Am I tempting fate by making some changes (adding Trackback, removing some badges, adding monthly archive links)? Yes.
Well, updates are still going through, and I like monthly links, but the Trackback addition is still problematic. The ping went out fine to at least one site, but for anyone who reads the site, rather than the RSS feed, there is a weird Macro error showing on the page. Turning Trackback on and off in the Radio prefs hasn’t changed anything in the display. I’ll dig a bit more, and then back to bed.
Posted to the Discussion group. We’ll see.
