Category Pages broken after moving from Localhost

Hello,

I’m developing with the Understrap theme. I have my theme built and working well locally. However, after using the duplicator plugin and installing this on my test server, everything works besides my category pages. What could be going wrong here since it works perfectly locally, just not when migrated up to the web?
