I am using a Wordpress plugin called 'Donate Plus'. This plugin hasn't been updated in a while, and some users have been having difficulty with it, including myself. I have fixed all of the issues, apart from one, and that is that I am getting a 404 error for the IPNs, i.e. when I go to look at my IPN History in PayPal, all transactions show as 'retrying', with HTTP response code 404.
As I understand it, a 404 error means that the page can't be found. The Notification URL is correct:
[url removed, login to view]
And the page exists!
It has also been suggested to me that the 404 error can be caused by the script not returning the same data to PayPal that it receives.
Payments are getting sent through OK,
Can anyone help as we need the features that this plugin has ?
Thanx in advance
