    There is an error about “Strict-Transport-Security´╝ÜThis site was served over HTTP and did not redirect to HTTPS.”
    There is an error about “Warning: Unnecessary HSTS header over HTTP”

    Hi William,

    have you enabled a redirect setting in the plugin settings (Settings->SSL->Settings)? That should redirect the site to https:// and solve the first error. Likely the HSTS header will then be served over https:// as well to fix the second error.

    Hello Mark,

    After then I re-enable SSL and HSTS and waiting for a while, it finally works. Now my site passed the check list of the header scan. Thank you!
