<p class="MsoNormal">It sounds like you stopped OMERO.web successfully, I can't think of anything else that would be running other than django. The traceback error is occurring in the OMERO.web 404 error handler- it looks like the logging module in Python 2.4
doesn't support the additional 'extra' parameter used in omeroweb/feedback/views.py:160. Unfortunately this makes it difficult to figure out what the exact error is!<o:p></o:p></p>

<p class="MsoNormal">You're right, I should've said OMEROweb.log. The fact that it's empty is a bit strange though. Is it possible you've got an old OMERO.web running from a previous server upgrade? Could you run `omero web stop`, then verify all relevant processes
are killed (you can use something like `ps -ef | grep django` to check). If there are any still present you can try killing them manually, then restart OMERO.web?<o:p></o:p></p>

<div>
<p class="MsoNormal">If that doesn't work then could you copy and paste the error message from the dialog- if there's no private information it would be helpful if you could CC the ome-users list, so that people don't see a hanging conversation. If we still
can't figure out the problem then server credentials could be useful.<o:p></o:p></p>
