Are you talking about user panel (dungog)
which is accessed via
https://yourdomain/user-manageror user manager (dmay) contrib, they are different.
What rpm did you install ?
> You don't have permission to access /user-manager//cgi-bin/userpanel-> navigation on this server.
It odd to be calling the cgi-bin folder ?
What URL (exactly) are you using to access it ?
Although you said:
>When I try and log on using the IP address of the server I get the login
> screen, enter my username and password, which when takes to to the
> usual framed window of the sever
You did not answer my earlier question.
Are you trying to logon from a computer on the local network or from a computer at a remote location via Internet
Also if it is the dungog user panel user-manager contrib, then have you configured which users have access to which panels in server manager first.
