We have a SSL Certificate installed on our server and according to this URL -http://www.sslshopper.com/ssl-checker.html#hostname=gilcommunity.co... the certificate is installed correctly.

I installed the Force SSL addon, created a page, and added the Force SSL attribute to that page. When I visit the page it is blank and has no edit bar. When I view source I get the following - <!-- SHTML Wrapper - 500 Server Error -->

Any help/advice on where to start looking would be much appreciated.

Thanks!
