first at all i wish you all a happy new year.
I have the following problem and that anyone can help me.
After a upgrade from 126.96.36.199 to 188.8.131.52 and few problems the shop is running.
But i can’t fix one problem.
If i want open an order e.g. http://domain.tld/index.php/admin/sales_order/view/order_id/123/ i get only a white page.
I have activated in index.php “ini_set(’display_errors’, 1);” and got the following error:
Fatal error: Undefined class constant 'ACTION_FLAG_PRODUCTS_PERMISSION_DENIED' in /var/www/vhosts/directory-to-shop/app/code/core/Mage/Adminhtml/controllers/Sales/OrderController.php on line 119
Anyone know the solution for this problem?
Thanks in advance!!
