Please excuse my newbie-ness. I've recently done a fresh drupal 7 install with Corked Screwer as the only installed theme. This issue that I'm having is that I have content blocks in each of the Footer 1st, 2nd, 3rd and 4th regions on the front page only. In Chrome, they render just fine. In Firefox, IE9 and Safari...Nothing. Not empty space, just not there leaving me confused as hell. What other information can I convey to help someone help me? Thanks.
