ive been getting this on and off too for years.
had some last night.
my paypal , sales are still going through.
Im HOPING as per previous comment, it is a) out of stock items b ) i have items live, but order disabled.
i have every country enabled and not restricted
abandoned cart at same times of paypal errors are "0" with 0 products.
it is a blank report : "A client has encountered a problem with the module PayPalAPI, see the report"
if it is a hack, i still dont want anyone getting this far
any help is appreciated.
or am i currently the only person using PS now
