Hi there,
Please try to add this code in Custom > JS:
WebFontConfig = {
google: { families: [ 'Lato:400,100,700,300:latin' ] }
};
(function() {
var wf = document.createElement('script');
wf.src = 'https://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
wf.type = 'text/javascript';
wf.async = 'true';
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(wf, s);
})();
Hope this helps.
