Thus, it can't know what the handler root is. Using: DocumentRoot /var/www/html/carconsumption.com <Directory /var/www/html/carconsumption.com> SetHandler mod_python PythonHandler mod_python.publisher PythonDebug On PythonOption mod_python.importer.path "['~/mod']" </Directory> should work, as will: DocumentRoot /var/www/html/carconsumption.com SetHandler mod_python PythonHandler mod_python.publisher PythonDebug On PythonOption mod_python.importer.path "['/var/www/html/ carconsumption.com/mod']" Note, when inside a Location directive, '~/' will not work either as Location isn't associated with a directory. What I have to think about now is whether when both Directory and Location directives aren't being used, that '~/' maps to DocumentRoot. I never thought about this particular scenario.
