Finally got around to fixing bug that was preventing me from being
able to use multiple 'categories' in YAML header. Basic issue was
my use of "root" many months ago when setting up jekyll. This caused
problems when pages had multiple categories and were nested, thus 'root'
did not have the same number of levels to get to index. By doing the
correct thing of setting "site" and using site.url, problem solved!
