PayPal feed not working -'invalid XML'

After working fine forever, suddenly today my PayPal feed won’t work on account 6131458554. Just says ‘invalid XML’. Had a lot of transactions at an event today so really need to fix it Any ideas? Btw we didn’t change anything and it was working yesterday. Help would be appreciated. Thanks.


Where do you see the “Invalid XML” error (e.g. what page)? I’ve just taken a quick look at your account but I can’t see anything that shows this.
