When I read these messages, I checked one of my old websites that uses paypal integration services and found that it stopped working. Payments were getting processed but the results confirmation didn't work. This is on Coldfusion 8. Thanks to this thread I found the problem and fixed it.. but just to make it faster for others... the certificate needed is the Verisign G5 certificate which you can get at https://knowledge.verisign.com/support/mpki-for-ssl-support/index?page=content&actp=CROSSLINK&id=SO5624
To see if you have it installed - and to install it if you don't, use: https://github.com/webdevsourcerer/CF-CertMan and install the version for your coldfusion version. After installing, you need to restart the cold fusion service. For those that like details, the paypal notice is at https://ppmts.custhelp.com/ci/fattach/get/471495/1425083092/redirect/1/filename/2015%20Merchant%20Security%20System%20Upgrade%20Guide%20(U.S.%20English).pdf Thanks ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:360367 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
