Error with paypal express

I installed this on my site a few months back and now I test it out and it doesn't work. The api settings are correct.

After clicking checkout button I get this error:

Warning: array_merge() [function.array-merge]: Argument #1 is not an array in /home/nrscoati/public_html/sipwnc/includes/modules/payment/paypalwpp.php on line 1467

See if that helps you out ... :smile:

Sounds like you're using an OLD version of Zen Cart that has some bugs in the Express Checkout code.
Upgrade to 1.3.8a or apply the applicable patch for the version you're using.

I am using 1.37 which is what the module was made for. It used to work fine, not sure what happened.

v1.3.7 had lots of PayPal bugs. Many patches were issued for it. The latest is here: http://www.zen-cart.com/forum/showthread.php?t=56216 ... The patches were also rolled up into v1.3.7.1, and v1.3.8a includes all the PayPal patches and year's worth of other fixes.
