Slider and Infinite Scroll stopped working

Hello, I am using the most recent version of Pinboard. Everything has been working fine, but suddenly both my slider and infinite scroll stopped working simultaneously. I now have only a static image in the slider (no forward/back arrows, and it does not cycle through the images), and the infinite scroll has disappeared (now it only says Load More Articles at the bottom of the page).

In addition, the posts grid does not align on my home page.

I have not changed any settings recently. The settings are still set to enable both of these features. Has anyone else experienced this or does anyone have a solution?

Thanks for any help.
