<div>Hi John</div>
<div><br>
</div>
<div>I’m glad you’ve got it working! Your diagnostics look fine, so unless the problem re-appears I don’t think there’s anything else we can do.</div>

If this works the server error 500 message should be more informative, and you’ll hopefully have a warning message in OMEROweb.log.<o:p></o:p></div>

2. Go back to basics. Are you able to setup OMERO.web in development mode instead of running via Apache?<o:p></o:p></div>

omero config set omero.web.application_server development<o:p></o:p></div>

</div>
<div>
<div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
Restart, and see if the problems still occur using<span class="Apple-converted-space"> </span><a href="http://server:4080/" style="color: purple; text-decoration: underline;">http://server:4080/</a><o:p></o:p></div>

<div>
<div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
If you need to keep the main instance running one thing you could try is running a second OMERO.web in development mode (but connecting to the same OMERO.server). This isn’t ideal, since the OMERO sessions will be shared between both OMERO.web instances:<o:p></o:p></div>

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></div>

Could you check your Apache logs for clues?<o:p></o:p></div>

<div>
<div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">

One other thing you could try is enabling debug mode in OMERO.web to see if that gives any additional information:<o:p></o:p></div>

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></div>

</div>
<div>
<div style="margin: 0cm 0cm 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
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></div>
