Blog Posts not displaying on page

## Please summarize your question in one sentence
Blog posts not displaying on page but entries exist in database

## Give a more extended description
I installed this module on a DNN v 08.00.04 site (module version 6.4.1). I tried making a few test blog posts, but nothing shows up on the page. If I go under Manage>Posts I can see all the posts that were made and they are all published, but nothing shows in the default blog list.

## Steps to reproduce (if needed)

## Other comments or remarks
I'm using this module successfully on another site (a DNN 8.5 Evoq Basic site) so I get how it works. I compared module settings from that site and everything seems the same. No console errors in Chrome. If I add a second version of the module to the page (to use a different template) an error shows saying: shCore.jsUncaught Error: can't load XRegExp twice in the same frame
