^{Originally posted by **tonydream888** February 23, 2024} Our website enabled “Cross-Origin Isolation”, so all resources(css, font, etc) on your server (use.fontawesome.com) are blocked by browser(Firefox, etc)! To fix the problem, please add the following http response header to your server: Cross-Origin-Resource-Policy: cross-origin that header will tell browser that your server give clear permission to other servers to access resources(css, etc) on your server. Thanks!
