Mixed Content Exception in Wordpress

问题

I'm getting the following error when submitting a Ninja form that was integrated to the wordpress site.

Mixed Content: The page at 'https://my.domain/event/test-page/' was loaded over HTTPS, but requested an insecure XMLHttpRequest endpoint 'http://my.domain/wp-admin/admin-ajax.php'. This request has been blocked; the content must be served over HTTPS. 

That is the only error that I'm getting. The site runs in HTTPS. A quick help is utmost appreciated.

Install the plugin Really Simple SSL. Once installed and activated, click on "Go Ahead!" Blue button to activate it.

You could try forcing all http requests to redirect to https. This is a blunt-force tool to solve issues like this, but not elegant. Place this in your .htaccess file above the #BEGIN WordPress line

    RewriteEngine On
    RewriteBase /
    RewriteCond %{HTTPS} off
    RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
