fontello icons are not showing properly

Dear alls,

We have a web (www.hotelsorollacentro.com) built with Enfold theme.

This is how web It is shown:

hotelsorollacentro.com is the main domain. But we have two more domains:

– hotelsorolla.com
– hotelsorollacentro.es

There is a unique hosting with wordpress and Enfold installation. This last two domains are pointing to the main domain as a redirection. Everything is showing all right except fontello fonts that appears like square icons, please see next image:

What can i do for showing properly fontello icons in the redirection domains?.

Thanks so much in advance for all your help.

Best regards,

Emilio
