Anyone knows the cause of the contents error

Hi,

Anyone knows the cause of the contents error.

Fatal error: Uncaught exception 'Exception' with message 'Error: Could not load model extension/total/discount_set!' in /home/teakecom/ocartdatapalctekjpr/storage/modification/system/engine/loader.php:97 Stack trace: #0 /home/teakecom/ocartdatapalctekjpr/storage/modification/catalog/controller/common/cart.php(34): Loader->model('extension/total...') #1 [internal function]: ControllerCommonCart->index(Array) #2 /home/teakecom/ocartdatapalctekjpr/storage/modification/system/engine/action.php(79): call_user_func_array(Array, Array) #3 /home/teakecom/ocartdatapalctekjpr/storage/modification/system/engine/loader.php(54): Action->execute(Object(Registry), Array) #4 /home/teakecom/ocartdatapalctekjpr/storage/modification/catalog/controller/common/header.php(80): Loader->controller('common/cart') #5 [internal function]: ControllerCommonHeader->index(Array) #6 /home/teakecom/ocartdatapalctekjpr/storage/modification/system/engine/action.php(79): call_user_func_array(Array, Array) #7 /home/teakecom/ocartdatapalctekjpr/storage/modifi in /home/teakecom/ocartdatapalctekjpr/storage/modification/system/engine/loader.php on line 97

Thank's
Hendra.

my guess would be your modification.

Just read the error, it always gives you all the info. At least the beginning of the message:

Could not load model extension/total/discount_set

This error is related to one of your order totals. Since it's not a part of default OpenCart contact extension developer on the matter.
