So I have a very strange issue going on here, First time the page loads it doesn't load any Google Fonts or the Icon font pack from the wordpress theme Divi. The content returns a 304 status code. Then if you click the logo (or any nav item) then all the fonts load correctly and return a status code of 200. But then if you hold shift and refresh any page they go back to 304 status and are not loading.
Made a quick screen share video to show the above. https://drive.google.com/file/d/15jAjqRP5PqjPYn69ueLfkTVC3k_ZVtJF/view
I have tried a few suggestion that I found on here on SO but nothing has helped. I tried to disable all Cache Plugins in Wordpress and a few .HTACCESS file mods
Header set Cache-Control "no-cache, no-store, must-revalidate"
Header set Pragma "no-cache"
Header set Expires 0
Any other suggestions on how to fix this?
