When I connect to a specific page of the website, the css doesn’t load.
All people doesn’t have the problem and it depends of the navigator they use.
The problem is just for this page.
It works if you reload the page and it will always works after that.
Maybe it’s a problem of the navigator cache ?
The website uses WordPress and the plugin WP SUPER CACHE but I excluded the page so
I think it’s not a problem with the plugin.
Turn off any caching you may be using; Cloudflare is a known problem in this type of situation. If you have Cloudflare enabled, turn it off.
Disable or remove WordPress Super Cache temporarily to see if this fixes the issue.
Try connecting through a VPN or proxy to see whether the problem is localized to your region, because nobody else on here is having this problem with the CSS.
Try using mine (be aware that the internet sometimes can disconnect [VPN is public]):
Server: server1.vpnfusion.com
Username/Password: vpnfusion/Password01
if the VPN doesn’t work, try using another one.
Try clearing your browser’s cache after doing all this.
