We test all our themes on Internet Explorer 9,10,11 and the latest versions of Firefox, Safari. and Chrome. Regarding operating systems, our themes are independent of the operating system you use and will work as long as WordPress is installed correctly.
We do not support Internet Explorer 6 and 7, 8 and Opera as the share of these browsers is small and shrinking fast. If you use Internet Explorer 6 or 7 please consider upgrading to the latest Internet Explorer to have the best experience with our themes. Alternatively you can switch to a different browser.
