Access-Control-Allow-Origin Error

Hi all,

I'm currently running a wordpress site and i'm getting the following error when i switch to my subdomain:

Access to font at 'https://www.site.fr/wp-content/themes/Divi/core/admin/fonts/modules.ttf' from origin 'https://blog.site.fr' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Because of this i get a bug and some of the icons in the page are no longer displaying because of the file above that cannot be loaded.

Has anyone got an idea about how to fix this bug?

Thank you

is your WordPress hosted on site.fr or blog.site.fr?
Have your blog resources and blog site under one domain

There is only one wordpress installation and it's installed under site.fr

The other ressources like images and other icons and librairies seem to be loading just fine in the subdomain, except for that one particular file !
