Hi,
It is because your REAL server is served via HTTPS and the GOOGLE font is loading via HTTP. This is why.
Open this PHP file:
/templates/flexible_coolmart/flexible/systems/joomla/layouts/head.php
and look for this expression:
http://fonts.googleapis.com/.....
(you will find this expression in many lines. Use CTRL+F to find them all. and Replace them all with this:
https://fonts.googleapis.com/.....
(load the Google Fonts through HTTPS protocol. And everything will be good to go)
If you like CoolMart and satisfied with the support you have received, please "write a review" on:

It won't take more than 2 minutes from you but it is extremely important for us.
Thanks in advance!
