Error when trying to get Google Fonts

Hi! i really like your plugin and i really want to have it on my site.

But it happens to be that it displays an error message on the console:

GET https://fonts.googleapis.com/css?family=dashicons net::ERR_ABORTED 400
asset @ caxton-utils.min.js?ver=1.26.0:1
loadFonts @ caxton-utils.min.js?ver=1.26.0:1
newContentManager @ caxton-utils.min.js?ver=1.26.0:1

Is there a way to solve it?

Cheers!
