Time for action - setting up SSL in PrestaShop
Let's do it.
1. Click on the Preferences tab.
2. For the fourth item in the list of options (Enable SSL), select Yes.
3. Scroll to the bottom of the page and click on Save.
4. Now go to your shop front, and click on Log in on your account or similar and notice the https:// at the front of the web address in your browser.
What just happened?
Your customers' vital details are now encrypted by SSL. If you are going to use PayPal as your payment provider, then the customers' financial details are kept secure by PayPal, even if you opted not to use SSL on your website.
