Hi. Imbalance 2 categories no longer loads posts underneath when clicking “Load more posts” button of page. Instead it takes user to a new page/window.
My settings are Settings > Reading >
Blog pages show at most  posts
Syndication feeds show the most recent  items
To infinity and beyond[unchecked] Scroll Infinitely
Is there any way have categories load and flow on a single page like they used to?
PS: When the Scroll Infinitely is checked, the front page shudders horribly and doubles up some of the posts.
The blog I need help with is boscutti.com.
