Thanks for your reply. Have you tried and added products to the cart? The header is only broken when I added to the cart. Maybe the problem is I use version 5.1.7 for windows? Unfortunately the latest version of Safari is 5.1.7.
Yes, version 5.1.7 for windows is a problem, it’s out of date. We do not support such old version of Safari browser because even developers of Safari does not support it. Don’t use Safari for Windows to test your site in Safari. Everything works fine if you use Mac!
