Hello

I am using a payment module for the spanish bank Caixa, and suddenly I am having this error in my logs:

PHP Fatal error: Class 'SHA' not found in /mysite.com/caixa_sermepa_process.php on line 95

the line 95 at caixa_sermepa_process.php is:

// load the selected shipping module

require(DIR_WS_CLASSES . 'shipping.php');

$shipping_modules = new shipping($_SESSION['shipping']);

I do have the file shipping.php under mysite.com/includes/classes/

Any idea what I sould do?

Thanks
