I am testing 2.1.0-rc.1
I am testing the mealtimes settings ( great feature by the way )
If you edit any of the menus and click save you receive the following error message, "The Mealtime field is required." Although mealtimes is set to Available all day.
If you select breakfast, lunch or dinner everything is okay, the error only shows if available all day is selected.
Just a thought but it would be an better feature if you could select your own times for the different mealtimes.
