Are you able to provide a packaged install of one of your demos to use as an example. I find we are spending more time than idea trying to figure out what is normal and what is not because of our custom css and style. We use yootheme Joy but any will really do, eg your Nano demo.
The problem is we are not allowed (of course) to give away the extensions that are installed in that package. There are a few installed external third party extension in PRO version + of course the YOOTheme template. - I will email YOOTheme and see if we cna make deal thoug with them perhaps.
