Hi Shu Liu,
Thank you very much, your advice helped me. I open file collab.props and change port=80 on a port=8080.
But I have new problem. I stopped on a Chapter 4: Configuring the server, page 63 Administration Guide.
When checking steps, on step “Configuring Required System Objects” showing status: “Error”.
What is the problem?
Thank you!
Sincerely, Vitaliy!
