Thanks @minimaluminium. I didn’t notice that the older posts were loading by themselves as I scrolled towards the bottom of the page. Is there a way to change this so that the user can click a “See more posts” button instead? I imagine I could just remove infinite-scroll.js but I would have to manually add a button to the page template and create my own script to load older posts either beneath or on another page, is that correct?
My reasoning is that I think the Casper theme looks great with 7 or 10 posts on the homepage (with one larger post at the top) but as you scroll down, three endless columns of posts begins to look rather bland and unappealing, in my opinion.
