Hello, this is just a comment in case it is helpful for someone else. I noticed that when I enabled multiple days to be displayed (Day 1, Day 2, etc..) the sidebar widget actually crammed all of the date information (October 12, 2010,October 13,2010...etc...) together on the right side and separately listed all of the weather details down the left. There seemed to be no connection between the date and the weather details. To enforce that it display the date and then details for each day I had to add the line
to the class
and this corrected the issue for me.
Before this change, I was experiencing the issue both on Firefox(3.6 and 4.0b6) and Chrome on my site http://www.palmvalleycondo.com and I also get the same error on http://www.tuxlog.de when I click the "Mehr..." on the widget on the right.
