More Posts Button

I feel like this was working and then suddenly poofed… I’m using the showposts=’5′ and it works fine. I’m separating by categories, so there are more than 5 posts in this category. However I’d like an “Older Posts” or “More posts” whatnot on the bottom of the page so people can navigate backward and forward. I could’ve sworn one was there previously and now it’s not and I can’t figure out how to get it back.

It exists on my blog pages, but not on my pages using this plugin.

Thanks for any help. I absolutely LOVE this plugin and I think it’s great!

Note: I have copied the template over to my theme because I’m using some custom templates. If that’s relevant.
