i am now trying to learn ruby, there was another developer that left and
i have a problem with our company website, www.italyabroad.com. when
clicking on wine on the navigation bar, the page does not open and there
is an error. when clicking on all other sections of the website (eg
food) that should use the same code, it works. i cannot understand where
is the problem, i have gone through plenty of books but my knowledge of
ruby is not up to it yet, any idea where is the error? thanks for all
