Using Local SSL
With Local SSL enabled as a plugin, your site will now open up as an encrypted page with the "lock" depicted next to the URL to indicate that the page is secure.
On some browsers (such as Firefox) the key is not stored in the operating system but in their own storage. You will be presented with a "Your connection is not secure".
Click the Open Menu button on the far right of the browser. Click the Preferences link on Mac or the Options menu on Windows.
Next click the Privacy & Security link.
Scroll to the bottom where you will find Certificates.
Click the [ View Certificates... ] button
Click the [ Import... ] button and browse to your ds-plugins folder
Then the local-ssl folder
Select the ServerPressCA.crt file and [ Open ]
Check the box for "Trust this CA to identify websites." [ OK ]
You will only have to do this one time.
