I moved the folders with all of the old WA stuff to a different location, as they were actually causing issues with newer pages that I was creating (I guess that they weren't updating some files because the older ones were already there.) As such I moved all of the stylesheets as well, as I guess they have more or less been abandoned (Pacifica, etc.) I wondered if they would convert to something new.
But it looks like I'll have to move the stylesheets back for those. It would be nice if there was a way to update them to the newer styles, or if the legacy styles existed in the newer system so that my backend could all look the same without a giant pile of work. :)
