I have two virtual servers, running almost identical Drupal 6.2 installs. On one of them I can use OpenID to log and on the other I can’t. It just fails with no error.
So there is something different between these two virtual server setups, but I can’t figure it out.
I did find that I had checked the box "Webmin login enabled" in Enabled Features on the server that is not working. I unchecked the box to make it just like the one that is working, but it is still not working.
Is there something in VirtualMin and or WebMin that might be blocking OpenID from communicating back to this Virtual Server?
