Older mod_python versions

mod_python versions 2.7.10, 3.0.4 and 3.1.2b have a bug in apache.resolve_object. This bug was reported to the mod_python maintainers and has been fixed in the 3.1.3 release. The best fix for this is to update to the current release. However if you are unable to do this there are 2 possible solutions:

1. Use a wrapper script

MoinMoin come with a moinmodpy.py wrapper script, and this could be used by changing the PythonPath and PythonHandler directives as shown in the moinmodpy.htaccess file.

2. Fix mod_python

mod_python has a small resolver bug in versions 2.7.10, 3.0.4 and 3.1.2b. The method resolve_object in mod_python/apache.py checks the wrong object, and so the lookup for RequestModPy.run fails.

To fix it you need to change the method resolve_object (around line 551 for mod_python 3.1.2b) from 

        if silent and not hasattr(module, obj_str):
            return None

to 

        if silent and not hasattr(obj, obj_str):
            return None
