Rodrigo,
Unfortunately, this email is not going to help you much, except to let you
know, that I have just had the same problem and have posted this to cobalt
users. You can find my message below:
I was updating my Raq4 and installing new packages from the Cobalt download
site. All went well until I installed either Raq4-All-System-1.0.1.9447.pkg
or Raq4-All-Security-1.0.2-8762.pkg.
I cannot now access my server management interface. I get the message "The
server encountered an internal error or misconfiguration and was unable to
complete your request".
Also, every 15 minutes I receive the message from my server, "PostSQL server
is down and cannot be restarted".
Can anybody please help?
