Hey there,
I am really sorry for the delay of this reply as it is a weekend for us here.
I've checked in your site, it seems like something is not right when you enabled Optimize CSS/JS from your current template, even your homepage also get affected , you can check my attached screenshot below.
Once I disabled those optimize setting from your template, it seems work fine now, can you give it a check?
If that is the thing, i would suggest you consult with your current template provider regarding this.
