Hello,

Clear Cache Plugin or Server Cache:

If you are using a cache plugin such as W3 Total Cache or WP Super Cache plugin. You will need to clear it’s cache content in order for the front end content to be updated.

If your web hosting company has a server cache, you will need to clear it in order for your content to be updated on front end. You will need to contact your web hosting company, if you are not sure if there is any server cache on your web hosting package.

I can also see that your site CSS is minified, Please once check without minify the CSS as well.

I am not able to see those Icons on your site because you have not turned ON the header Top as shown in this screenshot: https://screenshot.net/mep2lc1

If you are using a Content Delivery Network(CDN)

If you are using a Content Delivery Network ( CDN ) to load your font files, you will need to contact your CDN provider and ask them for the codes to add in your .htaccess to enable Cross Origin Resource Sharing.

The is an example from a CDN provider.

You will need to contact your web hosting company for assistance, if you do not know what is a .htaccess file or how to alter it properly. Doing it incorrectly will cause internal errors on your web server and crash your site.

Best Regards.
