This cloud wiki setting specifies a path where the server should retrieve its stylesheet for CSS-aware clients. This stylesheet provides much of the layout information for the wiki interface, and can be used to customize the look of your wiki.
Even if cache-stylesheets is set to "yes", you should reboot the server after changing this setting. Cloud Wiki, as of 1.0, caches configuration settings on first access.
