and first I want to thank this forum, since it's helped me tons already.
Now I started using the Salient (http://themeforest.net/item/salient-responsive-multipurpose-theme/4363266) theme these days which I downloaded from themeforest. As said, it's fine on Chrome, but Safari and Firefox are not displaying it correctly. Even though there is something, since scrolling is possible.
