I upgraded from 2.0.5 to 2.0.6 following the instructions to the letter. It appears all went well except....
Everything in my sidebar is the way it was, although I now have the following message in the Sidebar box on the Sidebar Widgets page.
Your theme will display its usual sidebar when this box is empty. Dragging widgets into this box will replace the usual sidebar with your customized sidebar.
I do not recall it being there before. More important, I cannot drag or drop any of the boxes that are in the Sidebar box or the Available Widgets box. I get the "four arrows" symbol but cannot move the boxes with it.
Any suggestions? I did not replace or do anything to sidebar.php in the folder for the theme (Blue Horizon 3.0 by Kaushal Sheth) and had no problems using Sidebar Widgets prior to the upgrade.
