hi all, i am having a issue when completing a payment using paypal standard plugin, everything seems to be setup correctly on nop (i have copied the plugin and setup from a working site) but when i land on paypal.com and click the pay button i get a 404 error with message 0 and error, we are experiencing technical difficulties blah blah.... i first saw this last week and presummed it was a paypal problem so left it for a couple of days, but the error is still there after 6 days so i checked another working site and got no error. this leads me to believe the problem is maybe with the PDT handler, is there anyway to confirm this is working ? or has anyone seen this problem before ?
thanks.
