The new Flatplus layout, based on the default Flat layout but has many more features.
We have also removed tables where possible and replaced with divs, making this a very responsive template.
Please note, this layout has been tested with the Default Joomla! 3.x prostar and some other template. But if it's not quite right on your site, then ask for assistance in the forms and we will happily take a look to see what is happening.
