I have a mystery here, and I hope to de-mystify it with your help.
The SSL cert for acceptid.com works fine in almost all browsers. But it is "not trusted"
* in Safari on the iPhone or iPad (works fine on Safari on OSX)
* in some installations of Chrome on OSX, but not others (works fine for my Mac but not for others)
The SslLabs site checks it out fine. There is no error message or any information that I can find in the browsers in which it does not work which might indicate any hint of any kind what's going on.
And the kicker: www.acceptid.com seems to work on all browsers, which uses the same cert on the same server.
I'm truly mystified.
