[Buildbot-devel] Force Build Button problems ...

[Kiffin Gish]

Hi there.

If I try to enable the force build button as follows:

# -----
from buildbot.status import html
c['status'].append(html.WebStatus(http_port=3001, allowForce=True))

from buildbot.status.html import WebStatus
c['status'].append(WebStatus(3001))
# -----

I get the following error message when I start buildbot:

# -----

The buildmaster took more than 10 seconds to start, so we were unable to
confirm that it started correctly. Please 'tail twistd.log' and look for
a
line that says 'configuration update complete' to verify correct
startup.

What's going wrong and how can I fix this?
