A rather perplexing issue has arisen. It took me a little while to work out why my .CSS was working fine on the production server but not on the development (Wampserver) server. The following:
works fine on the production server but, for some reason, it does not seem to work on Wampserver - which is a real pain. I can get the styles to load by "include"ing the stylesheet but I don't really want to do things that way.
Does anyone have any ideas where I can "tweak" Wampserver to get the relative link to work?
