Problems with paypal express global vars?


Recommended Posts



I have recently installed paypal to one of our sites running an old version (1.2) of osc. All fine apart from the 'checkout_confirmation' file needed to be updated.


The problem is that I am now trying to install the same module onto another site which runs on a different server and without success.


When trying the API test I get the 'your configuration is not correct' page, however the array underneath which usually contains all the info is completely empty! I know the API settings are correct and work OK on the other site.


Equally, the diagnostic e-mail contains none of the variables - again everything is empty!


The only difference between the 2 sites is the PHP version they are running. The site with the problems is running PHP V.4. not v5


Does anybody know if this could be causing the problems? or maybe it has something to do with global vars?


Any help would be greatly apreciated.

I'm having a similar issue - when you click check out the page simply refreshes and the url gets to changed to




the api test gives me this:




The PayPal Express Checkout credentials are not set up correctly for live production use.

array(0) {




and the debug email gives me this:








Whats strange is that the site has been working fine for months and all of a sudden has started producing this error!


Can anyone help?

I have the same problem, but it isn't when someone tries to pay the first time. It's more like when they want to pay again for something.

Once the hit the error (red bar with nothing in it), it won't work for anything until they log out and back in.

I get a PayPal Express Debug E-mail with nothing but:







I have no idea what to do to fix it.

I have turned on "Display with tax".
