I have a SSL Cert installed and site was setup with it freshly. I just created a Sub site using sub directories and I also have a htaccess redirect from http:// to https:// installed.
the URL on You have 13 days left in your Premium Vendor free trial. Checkout now to prevent losing Premium Vendor features » is http://www.xxxxxxxx.com/premium-vendors/?bid=2
When I click the link it changes to https://www.xxxxxxxx.com/?bid=2

I have in domain setting
Would you like to force https in login and admin pages: YES
Would you like to force http/https in front-end pages: Force https

How do I make the upgrade link work both HTTPS:// and not change to another URL
thanks
