Hey there,

The red cross on the https is typically associated with incorrect or non-matching SSL certificate
you can read more about this here: https://smallbusiness.chron.com/rid-red-line-through-https-77455.html
I would suggest that you consult the party that issued the SSL certificate on your site, which is usually the webhosting provider.

By the way, it appears that there are no subscriptions associated with your account with our website. Do we have any faults on our end? In order to help you with this, could you please provide us the order reference and your username?

Thanks!
