Hi sitireggiocal,
Thanks for reaching to us.
As the square boxes are shown except of icons in your site to fix this try to regenerate the CSS from WoodMart > CSS generator.
But, that issue usually caused by cache or incorrect HTTP and HTTPS configuration: https://domain.com is the actual site URL, however, http://domain.com is used in Dashboard > Settings > General. In this case, it is necessary to configure URLs correctly or clear cache and check again.
If you have any questions please feel free to contact us.
Regards,
