[Zope-dev] zope 2.7.0: no tracebacks produced

I am making a big upgrade and moving my products from 2.3.1 on HP-UX to 2.7.0 on windows 2000 and can't get zope to produce any tracebacks when it encounters errors. I've checked all the log files and monitor stdout to no avail. All I get is a brief html message with error type and value and instructions to check the error log. In the zope.conf file I have debug-mode on <eventlog> level ALL <logfile> path $INSTANCE/log/event.log level ALL </logfile> </eventlog> <logger trace> level ALL <logfile> path STDOUT </logfile> </logger> Any help here would be much appreciated!
