Hi,
I have similar problem with the Fashion template.
The side bars (left and right) are not showing on Chrome (v21.0.1180.89) or safari (v6.0). It works great on firefox (14.0.1 and 15.0.1).
I'm on OS X 10.7.4 using MAMP 1.9 as local server.
it's as if these browser see a small screen even when the screen is large. Which results in hiding the category menu block on the left and the 2 right columns are shifted below the main content. And the main content is now 100% wide.
To add more info, note that this is happening on a default install of he fashion quick_start installation. Nothing else has been added or installed. Just a plain install of the fashion quick_start.
any idea how, what could cause this?
