First of all you need to ensure that you have created the following directory structure in the Data Dictionary: "ShareResources/Pages" (this needs to be 100% accurate or the pages won't be created). When you want to view the page you need to access /share/page/hrp/p/<page name> (for hybrid view that includes the header and footer) or /share/page/rp/p/<page name> for full page view (without the header and footer). Also, be aware that the page renderer does a search for the page name so there may be some eventual consistency issues with Solr in that the page might not be immediately available (keep refreshing until Solr indexes the new page node).
It's worth bearing in mind that the page creator isn't a product feature and is just a prototype/developer tool to showcase some of Aikau's capabilities.
