Watch out for people who are doing this, the move to HTTPS has made people show up everywhere offering to install “a SSL” (TLS certificate aka enabling HTTPS) at a low cost. HTTPS is FREE and any web developer can easily set it up using Cloudflare or using Let’s Encrypt. Only allow the people you trust to modify your site and server. If you are in doubt and did not setup your site contact your host or the person who help setup your site.
