We're going to be talking about security related issues this time.
Google is now talking about downgrading site in searches if they aren't using https. So, you'll want to start using certificates. You can switch your Joomla! site over to https with one setting, but you need a valid certificate to avoid getting error messages.
We'll look at Let's Encrypt, one of the widely available free SSL certificate sources. What can it do for you, what won't it, and how to get one and install it?
We'll also look at Akeeba Admin Tools - how it can help protect your Joomla! sites, and some configuration tips.
Once again we'll finish up with Sheldon giving some valuable insights - this time on the hows and whys of putting in background images on your pages.
