I have read the support page https://ww.wp.xz.cn/support/topic/how-to-add-security-headers-with-wpfc/.

Unfortunately, it does not work.

I am using Worlds Fastest Cache. I also have a premium version (inactive at the moment). I cannot find a way of implementing security headers for more than a “D” rating whilst WP Fastest Cache is active. This is through webpagetest.org and probely.

I have tried http headers plugin and direct htaccess methods. Normally these work. I have 5 other sites where I have the http security implemented with A+ ratings.

On this particular site. I am able to get A+ rating only when I deactivate the WP Fastest cache but no with it active.

I can setup with other caching plugins such as Litespeed. However, it does not achieve the same load speed on this site.

The site runs through Cloudflare if that helps. There are no other cache plugins active at the moment.

The security headers are after all other items and outside the dedicated section for
WP fastest Cache in the htaccess file. I even had paid a cyber security person to look at it and he could only get the headers working by switching off WP fastest Cache.

Please help. I would like to have both WP Fastest Cache and security headers.
