ISPConfig version: 2.2.10 - Setup per instructions
On a Fedora Core 3 perfect setup.
Somehow, this problem seems to have vanished on it's own. I'm not sure what caused it but I generated the SSL CSR again today for that web site and it didn't happen. I even re-booted after doing it to be sure. It might have been gremlins.
By the way, on the CSR topic is it possible to keep the CRT and KEY files that already exist intact? That is until the new CRT is received. Fortunately I had backup copies so the site can still operate under SSL until the new CRT is received.
