Redirecting a WordPress website from HTTP to HTTPS is not as easy as it should be. I have yet to understand why there isn’t a simple checkbox to complete this task. There’s also numerous references which provide inaccurate information of how to accomplish this task. I’ll explain how to accomplish this with Apache, Nginx, IIS, as well as some popular web hosting control panels. These configuration changes are not WordPress-specific and can be referenced for any type of website.  If you don’t already have a certificate, check out Let’s Encrypt to obtain a trusted certificate at no cost. In most cases Let’s Encrypt certificates can be easily requested from your CPanel or Plesk web hosting control panel.
