Has anyone had any problems with their Gregarius installation recently. When I went to the Gregarius main page this morning, my browser tried to download index.php rather than rendering it. That resolved itself eventually (by itself), but now I can't log on to my main page. I can get into the admin area, but I can't mark items as read. Also none of the favicons are showing for any of the feeds and there's a thin vertical line to the left of each item's title.
