Hi, I have already tried the fix which was found here http://www.kriesi.at/support/topic/right-sidebar-showing-at-the-bottom-of-page, however that is not the correct fix. After changing the custom.css I had the same problems like other where the checkout page has improper form tabs, they go behind each other.
Without applying fix the forms show up properly but then shop page is messed up. I humbly request you to fix this asap.
Here is the link to my affected website page : http://alienstore.in/?post_type=product
