Broken Padlock

Why does my site show as insecure?

A broken padlock is what you get when your website is not fully secured. It’s called a “broken padlock” because browsers used to show an image of a broken padlock in the address bar.

Firefox Insecure Cart

Some browsers will simply display a message saying “Not Secure” like this:

Insecure Cart

Common Causes of broken padlock.

Mixed Content

Mixed content means although the page is being referenced using SSL (i.e. it starts with https://), some of the internal references are non-SSL. Generally this indicates that you are loading images, fonts, CSS or JavaScript over http rather than https.

If you see a “Not Secure” message, but click on the message and see a valid certificate, the problem might be caused by mixed content.

Insecure Cart

If you do a “View Source” in your browser and search for “http://” you can often find the root cause quickly. If you need more help, the find http references plugin builds a report on issues like this.

Expired SSL Certificate

SSL certificates must be renewed, and you forget to renew (or the credit card you use to auto-renew is expired). You’ll get a broken padlock.

Clicking on the message will show a dialog like this:

Insecure Cart - invalid cert

Clicking on the Certificate line will show a dialog like this:
