Yeah, Nima, what Janine said is right, you broke your AOLserver.
AOLserver 3.4.2 is not supported by OpenACS, you need a version that
is, which means either 3.3+ad13 or 4.0. There are some particular
features (e.g., SSL) that might not quite be 100% in 4.0, but lot's of
OpenACS maintainers say they've been using AOLserver 4.0 for a long
time now so it should basically work. See the
AOLServer 4.0 Support in 5.0?
thread for more info.
