Recently dfp ads stoped showing up on category pages. On all other pages ads are shown. I am using Joomla and live site can be found at https://www.livno-online.com/

When I try to use ?google_console on pages where ads are not showing I only see window with message "Loading". Example at https://www.livno-online.com/zupanija?google_console

I also get error:

Uncaught (in promise) TypeError: g.toLowerCase is not a function

Also, when I moved my site to subdomain everything works fine.

Is this some kind issue with server or with DFP configuration?
