about security websites

Why are you managing a secure sitge if you know nothing about security?

Security 101
https:// is secure http:// is not

if you have a secure certificate installed on the server for the domain the only difference between secire and non-secure is the s

The message (noted above) is caused by being on a secure URL (https://) and accessing a non secure item via (http://) such as an image. The easiest way to avoid such messages is to use relative paths (/folder/image.gif rather than http://www.domain.com/folder/image.gif )in the HTML code.

To truly manage a secure site you need to know much much more than this, but no one will be able to tell you anything you know. Either buy a good book on SSL and/or read online about it.

Good Luck

You don't understand what Jamal is trying to tell you. As you say you know https pages are secure (well it means they are using a certificate so they are as secure as the certificate is). If you get a message that the page contains non-secure items like Jamal said the secure page is referencing non-secure items like images.
