Galleries and Slider not working

I haven’t touched my site in several days. It worked fine and appears to still work on my mobile. But when I logged in tonight and looked at my site on my PC, all of a sudden my slider images are all on top of each other. I couldn’t get it to work so I set the slider to only show one image. But the galleries also no longer show on any of the gallery pages. They work on my mobile, but not PC and I did some trouble shooting but I don’t think it’s an issue with Foo Gallery, especially since my header seems affected too. I have not updated WordPress. I deactivated and reactivated my plugins and cleared my cache. Same issue. I think it’s the template but wondering if anyone else is having the same issue.
