Can't use web2py debugger?

It shows me this when I try to start the debugger:

web2py online debugger Unsupported webserver working mode:

WARNING: This debugger may not work properly if you don't have a threaded webserver or you're using multiple daemon processes.
In development, use the default Rocket webserver that is currently supported by this debugger.
On production, you'll have to configure your webserver to use one process and multiple threads to use this debugger.

The below has been auto-generated for your Web2py project

import os import sys

add your project directory to the sys.path

project_home = u'/home/dgmanns/web2py/' if project_home not in sys.path: sys.path = [project_home] + sys.path

sys.stdout = sys.stderr os.chdir(project_home)

serve web2py via WSGI handler

from gluon.main import wsgibase as application

See this. You may have to look at the web2py tickets that it generates instead of using the debugger.
