I am getting a checkout failure on PerformanceHotline.com and the url to the failure page is not correct. It displays performancehorsehotline.comcheckout_failure.php/ in the address bar. I am using paypal payments pro. I have all the fields completed in the payment gateway section except processor which is blank. I do not have the enable 3-D secure box selected. I could possible have the signature incorrect. Where am I suppose to get the signature information from? ie What I am suppose to enter in the signature field.
