I use a service called SiteImprove to check for broken links and scripts (among other things), and on every page that uses GeneratePress, it brings up an error for the URL http://fonts.googleapis.com.
Looking in the source, I see this:
<link rel='dns-prefetch' href='//fonts.googleapis.com'>
as well as the specific stylesheet for the custom font I’m using.
The Google font in question IS coming up correctly, but the call to the API is being considered a broken link. Is there a theme issue, or (probably what’s going on) does SiteImprove just have trouble with that URL because it’s an API call? What do you think?
