Charles posted that he's away until Monday. But here's a similar problem I'm having.
I assume you are using a Mac and the Safari browser?

I had the same message a couple of days ago, and posted about it below.
When you click on "Show Details", it brings up the box attached in this post --

I clicked on "review the certificate" and it warned me that the site was possibly bogus (!), but I think it's because the ChipBoard migrated to another server.

Bottom line, I did click on the "Visit this Website" and it did sort-of load the ChipGuide start page, though NO PICS are showing at all. Neither the start page, nor any of the other pages show pics. (This may be the same problem that Doug Deems is having??)

I have reported the above to Charles in an email. I expect he'll look into it on Monday when he gets back.
