My website is http://comafungi.org. It uses the Modular theme: http://www.mojo-themes.com/item/modulartheme-a-multipurpose-wordpress-theme/
There should be four widgets and a copyright notice in the footer, underneath the Twitter feed. The widgets and copyright notice were displaying until recently. I did not change any settings that would have made the widgets and copyright notice disappear.
The only thing that I think could possibly have caused this problem is the most recent WordPress upgrade, though, to be honest, because upgrades are so painless, I don't remember when I upgraded. Is there a way to figure out if the upgrade caused the problem before going to the trouble of downgrading? Is there a way to determine when I upgraded (b/c if it was a while ago, I know that the upgrade didn't cause the problem)?
