Hi, thanks for your answer.
Here is a screenshot of the css part of the minify settings, you can see that minification of the css files is enabled.
I have also add the troublesome font files to the CDN’s rejected files list, and purged the CDN but it doesn’t seem to change anything.
Here is the the list of the files added to the excluded files :
{plugins_dir}/elementor/assets/lib/font-awesome/webfonts/fa-regular-400.ttf
{plugins_dir}/elementor/assets/lib/font-awesome/webfonts/fa-regular-400.woff
{plugins_dir}/elementor/assets/lib/font-awesome/webfonts/fa-regular-400.woff2
{plugins_dir}/elementor/assets/lib/font-awesome/webfonts/fa-solid-900.woff2
{plugins_dir}/miniorange-login-openid/includes/webfonts/fa-regular-400.ttf
{plugins_dir}/miniorange-login-openid/includes/webfonts/fa-regular-400.woff
{plugins_dir}/miniorange-login-openid/includes/webfonts/fa-regular-400.woff2
