Newer/Older posts links display same posts on every page

I am using a plugin called “Types” to generate custom post types for drink/food recipes. I want to show booth drink and food recipes on the same page. The posts are displaying fine, but for some reason, when you click “newer posts” or “older posts” it will bring you to a new page, but the new page will have the same posts as page 1. Anyone have any ideas? Thanks in advance!

URL rewrites and pagination

I must say that I am a complete nooby at WordPress custom URL rewrites. I have searched for past many days to find a clear explanation of how to determine and write correct pattern for URL rewrites. I have a custom page template that uses query var passed to it, e.g. http://example.com/pagename?user=username. In this “pagename” refers to the custom page template and “user” refers to the custom query var. I need this to be represented using the URL http://example.com/pagename/username.
