It’s pretty easy to turn on SSL in Joomla 1.5. You can turn it on for Administrators only, for the whole site, or for individual pages. If you have an SSL certificate, you should at least turn it on for the Administrators. That way, you can protect your administrator logins. If you allow users to register, you should turn on SSL for the user login and registration.
Note: In order to use SSL in Joomla, you need a dedicated IP address AND an SSL certificate. Contact your host if you don’t have these items.
To turn on Joomla SSL for your whole site
- From the Joomla admin menu, select Site > Global Configuration > Server.
- In the Force SSL list, select Entire Site.
- Click Apply.
This will force SSL for your entire website, Administrator and front end.
