I just want to access to LimeSurvey database. However, in my PHP code first line, I put require_once '/application/config.php' as a way to load up the LimeSurvey DB Information. But the page always return("No direct script access allowed"). And I check config.php file, and only when basepath is not defined can generate this problem.(if (!defined('BASEPATH')) exit('No direct script access allowed') So how and where to set the basepath. Thanks for everyone in advance here.
