Having problems with getting your website to run “https”. You’ve installed your SSL certificate. You’ve renamed your site to “http://” but you still just don’t get the padlock like you know you should.
Why No Padlock? to the rescue!
This tool will not only check your SSL certificate, but most importantly, it will scan the requested page and tell you what is causing your padlock to break. More often than not, it will be a mixed content error because you’re loading an image using an http request instead of an https request.
If you get stuck, you might find that the WordPress plugin Really Simple SSL may help you get the last of the issues wrapped up for your site.
