From now on the Voptop website (for all domains) is encrypted with an SSL certificate generated by "Let’s Encrypt". Currently you can choose by your self if you want to visit the website encrypted or not. Just our bug tracker (https://www.voptop.com/mantisBT) forces an SSL encryption and redirects you to HTTPS, so far.
In near future, we will redirect all HTTP traffic to HTTPS.
Thanks to the "Let's Encrypt" project for there great work!
