On the 14th, I can see several payment notifications.
One of them for example is the payment notification with the id 05B91690445140129
Normally, in the IPN history of your PayPal merchant account, you can access the details of the payment notification.
I see only two reasons why that payment notification wouldn't trigger the order status changing to confirmed:
- the amount paid and the total amount of the order are not exactly the same. This can happen if you have the "send order details" setting activated in your PayPal payment method. However, from what I can see in the log, this is apparently not the case.
- something blocked the update of the status. It could be a plugin or a mass action. So check if any plugin was added on the 11th or 12th or any mass action in the System>Mass actions menu. Also, it's possible it would be stopped by a PHP fatal error. So I would recommend checking the PHP error log. For example, if someone created a mass action with a "run PHP code" action and a "before an order is updated" trigger and the PHP code entered in the mass action is invalid, it could create that problem.
