Pagination not working for questions or answers

Background
I have AnsPress installed through the WordPress Plugins site, and am running version 3.0.7. I have the AskBug theme installed, version 1.9.

Problem
I have a page in wordpress, ANSPRESS_TITLE, and the permalink is set to example.com/forum.

If I go to that page, I see my list of anspress posts. I see the pagination at the bottom, and if I inspect the page 2 button, I see the link: example.com/forum/page/2.

However, when I click that link, it does not work. I just get sent to example.com/forum/.

If I go to an individual post (example.com/forum/question/test_question), and try to go to the next page of answers (example.com/forum/question/test_question/page/2), I also get redirected to example.com/forum/.

If I go to my wordpress Settings > Reading section, I have the following setup:

I have tried resaving permalinks, but that does not fix the problem. Any ideas?
