 * Hello,
 * The plugin worked great, I got HSTS preloaded, but then something happened and
   now I face problem with HSTS preload which states that the site has multiple 
   HSTS headers ([https://hstspreload.org/?domain=ladislav-antos.cz](https://hstspreload.org/?domain=ladislav-antos.cz)),
   when I check the headers I really see them twice, every header is doubled ([https://domsignal.com/test/h74c5ul404bru392zpfllmkssowruh3n](https://domsignal.com/test/h74c5ul404bru392zpfllmkssowruh3n)).
 * When I deactivate the plugin all of the headers disappear. So I think it is something
   with the plugin that makes the headers double.
 * How can I repair it?
 * Thanks in advance for your answers!

 * hi **[@ladisnek](https://wordpress.org/support/users/ladisnek/)**, thank you 
   for your topic and the time you took to write it, I am also trying with the contributors
   and your feedback to improve the plugin more and more.
 * After a check the duplicate headers itself don’t cause any issues on the performance
   side or to the website, going back to the check I confirm you that your site 
   uses well the plugin headers with A+ grade _(securityheaders.com),_ well also
   the result _(domsignal.com) _and on _HSTS preloaded _it appears that the domain
   described in the topic is correctly preloaded.
 * I am available for further questions or issues.
