The goal is to get a userfriendly structure of the url segments. Itshould behave as a tree hierarchy where the segment to the right is a level deeper into the sitemap.
/work points to a custom overviewpage of all projects
/work/%category% points to a specific client
(We use categories as the clientlist). e.g. /work/nike or /work/coca-cola-company. For this to work I use /work/ as a category base.
/work/%category%/%postname% goes to a specific project. This is where the problem lies whereas /work/ in both category base as in the permalink doesn’t seem to be allowed.
e.g. /work/nike/billboard-advertisments-time-square
/work/coca-cola-company/promo-campaign-summer-2012
