Checking with xhprof - unable to load

Hi,

I am trying to check some PHP for debugging and followed xhprof the installation guidelines on this old post: http://forums.cpanel.net/f42/installing-xhprof-php-function-call-debugging-252521.html#post1048751

I've managed to get everything installed, I have copied the xhprof directories to the relevant user account, however when I visit http://domain.com/xhprof/xhprof_html/list.php I get a 404 error. I have replaced domain.com with the relevant user account domain.

I can confirm the directories / files exist in that user account by viewing directory contents with an FTP program.

I can view http://domain.com/xhprof/ and it gives me the standard directory listing, however going one level deeper throws up the error 404.

Is there something simple I have missed?
