[Plugin: WordPress HTTPS (SSL)] unable to get secure site page to load

hello,
I am very hopeful to get this plugin working, but have been unsuccessful so far.

My ssl host is: secure122.inmotionhosting.com/~insigh40/

When I try to view the one page I set to secure, I get a page error:
The requested URL /~insigh40/services/bridal-party/ was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

If I add the domain name to this:
https://secure122.inmotionhosting.com/~insigh40/indirasalonspa.com/services/bridal-party/

I get the following page:
http://www.insightcreative.info/test/screenshot-shared-hosting-url.jpg

I am at a loss for how to resolve this issue? anyone? I appreciate your time to respond.
