Help with SSL certificate error on site

Site in question: [login to view URL] My problem: Some users report getting an SSL certificate problem. I can not reliably replicate it on my computer so don't know what exactly causes it. Seems to happen with older Firefox (ver 3). What I want from you: 1. Figure out how to successfully replicate it. That part you have to do as part of your bid - ie your bid would have to contain the description of the problem (ie what browser configuration causes the certificate error to show up) 2. You would have to solve it. This is probably something very simple - if YOU KNOW how SSL works. Let me stress - please DO NOT submit bids without first going to the site and REPLICATING THE PROBLEM. If you submit a bid without that part it will be dismissed. I am also not looking for free work - I will pay for your solving the issue. Simply knowing that the problem occurs with Firefox 3.6 doesn't help. Also pls don't bid above $30 - I think this is a 5 minute job for someone who knows what they are doing.
