UTF-8 Icon Issue

Is anyone else having an issue with the UTF-8 icons not always displaying properly? It is very random on my site.

Change browser

I have tried and have the issue with Firefox, Chrome, and IE. It may do it one moment, then I refresh the page and it's fixed. Then again I might refresh the page 3 or 4 times before it corrects itself.

As far as I know that problem doesn't happen only with OpenCart, I've seen it in other websites. Are you using a IIS server?

I have found that it appears to be related to the headers and font awesome. A way that seems to have resolved it is to add the following to your .htaccess file

<FilesMatch ".(ttf|otf|eot|woff)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
