[Skunkworks] JPGraph

Hi all, I am trying to display some graphs using JPGraph in PHP. I get the following error. *Chosen locale file ("lang/en.inc.php") for error messages does not exist or is not readable for the PHP process. Please make sure that the file exists and that the file permissions are such that the PHP process is allowed to read this file. * Can someone with knowledge in PHP and JPGraph please help. -- Walter.
