I'm trying to set up flat rate shipping. On the "Extensions > Shipping > Flat Rate" page it shows a "Storefront Icon" being needed.
I'm also getting this System Message: Language definition "default_flat_rate_shipping_shipping_storefront_icon" is missing for ""
There's no information in the Documentation about what this, what to do, etc. Please add information about the Storefront Icon, what it is, what size it needs to be, where it will be displayed, etc., etc.
Thank you
