For the site to work a php file named only cw_modules/init.php must be found using an include path defined in the we server configuration.
That means that the include path must contain the folder in which cw_modules/ is found.
Current include paths:
/var/www/webroot/cw/ext_libs/php
/usr/share/php
/var/www/webroot/cw
/var/www/webroot/cw/cw_code
.
