Python handler error returning "500 internal server error" in browser

[jdc@…]

Hi,

I was installing Trac and got this error returned:

[Fri Jul 18 11:39:14 2008] [error] [client 192.168.2.3] PythonHandler trac.web.modpython_frontend: Traceback (most recent call last):

This is my code in trac.conf

<Location /trac/testproject>
        SetHandler mod_python
        PythonHandler trac.web.modpython_frontend
        PythonOption TracEnv /tcs/trac/testproject
        PythonOption TracUriRoot /trac/testproject
</Location>

<Location "/trac/testproject/login">
        AuthType Basic
        AuthName "trac"
        AuthUserFile /tcs/trac/testproject.htpasswd
        Require valid-user
</Location>

Is there any more information required to solve this problem?

Well, you never know if that pastebin link will last for the few years to come… better include the actual error inline.

Chances are that your mod_python is still seeing some parts of an older (0.9 or 0.10) Trac installation.

Check your PYTHONPATH and check the following locations:

• /usr/lib/python2.4/site-packages/Trac-0.11-py2.4.egg/trac/util/compat.py (should be there)
• /usr/lib/python2.4/site-packages/trac (should not be there)
