I recently added an SSL certificate to my server and turned on SSL in Joomla.  When I load a page with a SIG Pro Plugin the browser reports that some of the page is not secure.  How can I resolve this issue so that SIG Pro content is secure.

my website is under construction.  It is:  www.vncsales.com
user name: webuser
Password: vncwebuser

Sorry but I cannot understand the necessity of SSL in your site. In addition SIG PRO contains images not content...

I need SSL to ensure password security.  I will also have content on my site that is confidential.  I can't put it on the site until I have SSL.

I had the same problem with IE 8 and IE 7 not displaying the images from the folder in SSL if user selected yes on the IE "not secure" popup. The following solved it.
Edit your configuration.php file (make sure that it is writable!) and change the live site setting from http to https:
example (line 20):See it using IE 7 or 8 at 179websites.com/templates.html
