Hi Julian,

The above font path is giving 404 not found. It means that either the file doesn’t exists or you server have blocked it from loading. Can you please keep this in your htaccess file and try ? The above link will not give 404 when the blocked is removed.
<FilesMatch "\.(ttf|otf|eot|woff|css)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
If this doesn’t work, please ask your host provider to enable font (woff and eot format) for loading.
Thanks
