# Missing Security Headers

 * Hello,
 * I bought the pro version of Really Simple SSL and everything was working fine.
   Today, I saw a warning:
 * 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
    - HTTP Strict Transport Security
 * When I logged into the settings of my WordPress site, I found that I am unable
   to change any of the key information, as well as my license code not existing
   in the settings.
 * What is the solution to the problem? Since these were all working in the past,
   I don’t understand what happened in the last 48 hours that the plugin is now 
   popping errors and not allowing me to re-enter my licence code or change any 
   of the header setting. My license is valid until Nov 2023.
 * Thank you!
 * Regards,
 * Syed Khalid Muhammad

 * Hi [@commandeleven](https://wordpress.org/support/users/commandeleven/),
 * Please ensure that you have the latest versions of both the _Free _and _Pro _plugin
   enabled on the website; which will both allow you to enter/modify the license&
   use the _Pro_ features.
 * In any case; if I test your website URL via SecurityHeaders.com, it seems that
   just the _Permissions Policy _header is still missing. So, after enabling this
   header in the plugin’s settings you should be all good to go.
 * But please note that we’re only allowed to discuss the Free plugin on these forums,
   and as your question concerns features in the Pro plugin: please send us a message
   via [https://really-simple-ssl.com/support/](https://really-simple-ssl.com/support/)
   if you require further assistance, and we will be glad to help out.
 * Kind regards, Jarno
