Fatal error: Call to undefined function...

well, your paths are not correct.. you are using URL instead of a path
should be something like:

// Path to where mydms is located
var $_rootDir = "/home/user/public_html/dataroom/";

// Where the uploaded files are stored (best to choose a directory that
// is not accessible through your web-server)
var $_contentDir = "/home/user/public_html/dataroom/drdocs/";

// Path to adodb
var $_ADOdbPath = "/home/user/public_html/dataroom/adodb/";
