Hi,
As i check, your site is importing google font from file /templates/megastar/styles/blue/css/bootstrap.css
JA Font can't help you this case.
You should load google font on your html by using link
tag
<link href="https://fonts.googleapis.com/css?family=Montserrat:400,700|Open+Sans:400,300,700,400italic" rel="stylesheet">
