Cannot redeclare xtc_image()

[rsno]

Bekomme nach der Grundinstallation folgenden Fehler:

Fatal error: Cannot redeclare xtc_image() (previously declared in \\boswinfs04\home\users\web\b2756\ywh.myhost\myhos t\shop\inc\xtc_image.inc.php:21) in \\boswinfs04\home\users\web\b2756\ywh.myhost\shop\ inc\xtc_image.inc.php on line 59

Meine config.php sieht so aus:

define('HTTP_SERVER', 'http://www.myhost.at'); // eg, http://localhost - should not be empty for productive servers
define('HTTPS_SERVER', 'https://www.myhost.at'); // eg, https://localhost - should not be empty for productive servers
define('ENABLE_SSL', false); // secure webserver for checkout procedure?
define('DIR_WS_CATALOG', '/shop/'); // absolute path required
define('DIR_FS_DOCUMENT_ROOT', '//boswinfs04/home/users/web/b2756/ywh.myhost//myhost/shop/');
define('DIR_FS_CATALOG', '//boswinfs04/home/users/web/b2756/ywh.myhost//myhost/shop/');

define('DIR_FS_DOWNLOAD', DIR_FS_CATALOG . 'download/');
define('DIR_FS_DOWNLOAD_PUBLIC', DIR_FS_CATALOG . 'pub/');

Irgendwelche Ideen?

Den Tip mit
require_once(DIR_FS_INC.'xtc_output_warning.inc.ph p');
require_once(DIR_FS_INC.'xtc_image.inc.php');
require_once(DIR_FS_INC.'xtc_parse_input_field_dat a.inc.php');
require_once(DIR_FS_INC.'xtc_draw_separator.inc.ph p');
hab ich schon ausprobiert - leider kein Erfolg
