When you visit a secure page and the lock does not display in the lower right-hand corner of the browser, this is because the browser has detected that not all elements on the page are secure. When a page is called via a secure SSL call, the browser checks to make sure that all the elements on it can be loaded securely. To ensure that the lock appears in the browser (indicating that the page is secure), please re-write all your pages links with https calls, and do not load any external pages.
For instance, to set up and use your shared SSL certificate for your file.html page, simply use:
https://membername.sslpowered.com/filename.html (where "membername" is your Netfirms username) as your address (URL) OR https://yourdomain.com.sslpowered.com/filename.html
If you are not sure what your member name is, it is the same name you use to log into your FTP site.
NOTE: You must subscribe to either the Advantage Plan or Business Plan for SSL support.
