We recommend using Firefox when operating the admin areas of OptimizePress. This is because it handles Javascript best, which means faster performance when editing pages.
We have also tested OptimizePress on Internet Explorer 8, 9, and 10, and the latest version of Chrome.
Regarding operating systems, OptimizePress is independent of the operating system you use and will work as long as WordPress is installed correctly.
We no longer support Internet Explorer 6 and 7
Please Note: Currently our Live Editor page building system is not compatible with Safari for editing pages (your pages will display fine on Safari for your visitors, but we recommend that you do not edit them with the Safari browser).
