Pagination broken

Hello,
Kind of a rookie here.

So if I’m browsing a category – https://believerscenter.com/category/yx-podcast/ – I can use the pagination and go to the older entries. But if I omit the ‘category’ from the URL – https://believerscenter.com/yx-podcast/ – everything looks fine, but trying to go to page 2 (or any other page) results in a 404.

Any idea why that would be?

Thanks,
– David
