function do_shortcode is disabled in WordPress for https.

I have been told by one of my plugin’s support team, that the “function do_shortcode” has been disabled in WordPress when I use my installed security certificate (https). How can I go about enabling this? I am trying to redirect my entire domain to https, but when I do, any plugin that uses shortcodes stops functioning properly. Is this something that needs to be fixed by my hosting company, or something that I need to do?

If it is something I need to change in shortcodes.php, does anyone know what code needs to be added to make shortcodes functional with https?

When I access “wp-admin” with https, the shortcodes are not even generated. I know a little php, but my experience does not go beyond added things to functions.php.

Here are the respective links for my test page:

Thanks in advance for any help.
