Hi guys, I'm new to October - so far I'm really enjoying it and Stellar is SUPER clean! My main goal is to use a version of October as a "simple" blog (https://devblog.willstocks.com/). I've set the "blog_post" page to have the url: "/:page?" but this results in two issues:

Pagination doesn't actually work... at all! If I attempt to change it, any url I call then call (https://devblog.willstocks.com/404 for example) just shows the list of blog posts, rather than the error page.

TL;DR - For some reason, pagination isn't working?
