Thanks for your response. Taking the points in turn:
Can you confirm that you are using the same Apache instance for PHP at the
same time as wanting to use it for Python? Yes that is correct

Post the details of the over VirtualHost.
Full content of the *httpd-vhosts.conf* file is as follows:
<VirtualHost *:80>
ServerName localhost
DocumentRoot c:/wamp/www
<Directory "c:/wamp/www/">
Options +Indexes +Includes +FollowSymLinks +MultiViews
AllowOverride All
Require local
</Directory>
</VirtualHost>
#
<VirtualHost *:80>
ServerName localhost
WSGIScriptAlias /test C:/wamp/www/wsgi_script/test.wsgi
<Directory C:/wamp/www/wsgi_script>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
Also, what is DocumentRoot set to in the httpd.conf file? The code line is
*DocumentRoot
"${INSTALL_DIR}/www"* and earlier there is *Define INSTALL_DIR c:/wamp*
which presumably defines the variable.
What did step 4 output and what did you add to the httpd.conf file? The
following:
LoadFile "c:/python36/python36.dll"
LoadModule wsgi_module
"c:/python36/lib/site-packages/mod_wsgi/server/mod_wsgi.cp36-win_amd64.pyd"
WSGIPythonHome "c:/python36"
Is there any existing LoadModule line for wsgi_module anywhere else in the
httpd.conf file. Answer no - confirmed by file search
Hope that sheds some light.
