Regarding WordPress, there is one item that needs improvement to enhance its security, as indicated by the following message:
“Recommended security headers are not all installed. Your website does not send all recommended security headers. Upgrade Insecure Requests, X-XSS-Protection, X-Content-Type-Options, Referrer-Policy, X-Frame-Options, Permissions-Policy.”
I have the Really Simple SSL Pro version, and according to the plugin, my site has an A+ status.
What can be done to address this security message? Do I need to enter a code in the .htaccess file? I also tried deactivating all extensions except for Really Simple SSL to check if there is any conflict between plugins, but the message still appears.
Thank you in advance.
