I’ve found out that inf Ultimate (Free) theme cross-browsing isn’t working.
My website in differnt Google Chrome browsers shows different fonts, looks more differnt in Opera and even more diffirent types of IE.
For example IE 9 can’t see my menu buttuns untill I’ll put my mouse on them.
Did you customize any code? If not then first of all deactivate all the plugins that you have installed in your dashboard and check whether the same problems pursuits or not. Please go through our demo site too whether its working fine or not. If its working fine in our demo then it also must work fine in your site too.
