That’s ironic: I’ve always been keeping “Infinite scroll” option on, but after it stopped working I selected, in the dropdown menu below, the “Numbered pagination” option. Now, before replying to you, I went checking if the infinite scroll option was still selected, and – I don’t know why – I tried to switch on “Next Page/Prev Page” in the menu below.
Result: Infinite scroll is now working again.
Thank you anyway
