My site is in loop (probably https redirects to http and then back) when "Keep HTTPS connection once a secure page is visited:" option is not selected. When selected everything is fine, but I don't want to have default https on. Now all pages are redirected to https in firefox and chrome. I have to delete all history in those browsers to have http back.
This happend after I installed Let's encrypt SSL certificate. Later I removed it and installed Comodo but situation didn't change. Can you give me some directions what to check. I have cs-cart 4.5.2 SP2
Thank you!
