entypo-fontello font not showing after update

Hi,
After updating to the latest version, on this website, the icons are not showing. See search and Icon boxes under slider:
http://www.phoenixvibrationcontrols.com/en/
Wordpress and plugins (WPML, Sucuri, BackWPup and Black Studio TinyMCE widget) are up to date.

I tried solution from this topic: https://kriesi.at/support/topic/entypo-fontello-font-not-showing-after-update/

What else can I do?

Thanks in advance,
Ariane
