Okay, I’ve deactivated all the plugins and see that it actually works fine, now. Guess it wasn’t a theme problem; just need to figure out which Plugin is affecting it. Thanks!
It seems like the problem is still there, even with the parent theme. It’s weird because when I inspected both pages, they both read as the same width (360px according to the inspector). I’ve dug through the css as best I could, but I’m unable to identify the problem.
Alright, well I did incorporate it into a child theme, but the problem still persists.
