Font Won’t Unbold In Page Templates (i.e. Archives)

Hello, just today, I re-uploaded iNove to my blogsite to rid my site of a small error in code. Although that error disappeared, unfortunately, none of my page templates survived the change. They all changed font in the process and now everything is bolded. Unfortunately, after digging in style.css for a few hours, I am unable to figure out how to change it. The font was also gigantic (size 30-ish), but I finally figured that one out.

For reference, here is the link to my site

Thanks.
