If you have web fonts on a subdomain seperate to the domain you are calling them, usual advice is to place the following into the .htaccess file for the subdomain
<IfModule mod_headers.c> <FilesMatch “.(eot|otf|ttc|ttf|woff|woff2)$”> Header set Access-Control-Allow-Origin “*” </FilesMatch> </IfModule>
If that doesn’t work, it’s likely the header module in apache isn’t enabled. Find out by creating a .htaccess file with just this line.
Header set Access-Control-Allow-Origin “*”
Try to view a web page. If you get errors, most likely the header module isn’t enabled in apache. Enable it from the command line like this
sudo a2enmod headers
then restart apache.
