I am getting two SSL related errors when using IE 7 and Firefox 2.0, but NOT with IE6.
1). with IE7, I can NOT invoke ANY SSL activity such as logging into my web site or loading ADMIN. Get error:
There is a problem with this website's security certificate.
This organization's certificate has been revoked.
Security certificate problems may indicate an attempt to fool you or intercept
any data you send to the server.
We recommend that you close this webpage and do not continue to this website.

2). Using Firefox- When trying to login as a site visitor or place an order, get a pop up box that reads:
"You have requested an encrypted page that contains some unencrypted information. Information that you see or enter on this page could easily be read by a third party. ".

I recently moved my site to another hosting service.
