Strange things are afoot. I am using a aweber subscription form in my side bar but since upgrading to the latest WP it appears at the bottom of the page.
I cannot say for certain that it was the upgrade that started the problem however, it did start about a week or so ago around the time of the upgrade.
I contacted aweber tech support and they suggested posting on wp.org as I'm doing now.
