I am deploying my web.py application on Apache2 with mod_wsgi.
Here is my virt_host file,
WSGIPythonPath /home/ubuntu/plotwatt/libplotwatt:/home/ubuntu/
According to the docs, you cannot use WSGIPythonPath when using daemon mode. Use the 'python-path' option to the WSGIDaemonProcess directive instead.
