 * Hi there,
 * We are migrating a number of sites over to the newest version of PHP and fixing
   compatibility issues and bugs along the way, this process is rather lengthy and
   has allowed us to find errors in some of the plugins we use.
 * The file with the undefined variable reference is download-manager/libs/class.
   Pagination.php in the show() function at line 169.
 * There is no default value assigned to the variable $e_id and WP_Debug throws 
   up a lot of errors.
 * If you could rectify this at some point that would be great.
 * Thank you,
    Connect.
