Invoice sent to buyers, system does not allow them to pay when they press Pay Now.

I sold a number of items on eBay last night. One buyer has attempted to pay following receiving his invoice but the system is not accepting his payment - first time said there was no postage charge on the invoice even though there is; second time said there was a fault with his address though I successfully sent him goods there a week ago.

PayPal is the payment processor, not Ebay. And PayPal was glitching last night (and may still be today), no doubt due to the huge increase in online shopping. All you can do is to tell your buyer to keep trying.
