$zc_valid = false;
}
$installed_modules[$module->sort_order] = $file;
} else {
$installed_modules[] = $file;

thanks in advance guys

Actually, it's quite simple ... you've got a misplaced file in your /includes/modules/shipping/ folder (namely product.php) and the system is unsuccessful in finding a matching language file for that module in the normal location for language files for shipping modules.

hey tanks for helping but product.php is in includes/module/shipping ?
so im now more confused

That's my point.
Zen Cart doesn't have an /includes/modules/shipping/product.php file.
I don't know how yours got there, but if you remove it your error message should go away.

thank for ur help all is sorted
