Then I try to access moodle but i get a screen saying
- Fatal error: main(): Failed opening required '' (include_path='.:/usr/local/lib/php') in /homepages/30/d130045270/htdocs/moodle/www/config.php on line 20
The way to test is to upload a file, say phpinfo.php with the contents
<?php phpinfo(); ?>and access http://whateveryourmoodlesite/phpinfo.php with a browser.
You should get a nicely formatted table with technical information.
