I had a bunch of problems getting the padlock to display on the interior pages of my site in Firefox even though in Chrome the padlock was always displayed. Same issue in Internet Explorer where that annoying bar would pop up saying "only displaying secure content" and then when you'd tell it to show everything the page still looked the same! :eek: We also couldn't get a redirect from within cPanel to function because of some "mystery" interference from my site.
