Error 500 When using Paypal Express checkout button

[patuga]

I could never complete an order on my store with the express checkout button. i thought that now after they added the button to the cart instead of only the product page, that this problem would get fixed.

i don't know why, but i always get an error 500 when i'm on the last step of the payment. i see the screen with the total amount, my info etc, but when i click continue an error 500 appears.

 

it seems this is an old problem. but no one has any information about it.

i get these errors:

all those errors are happening because of the address i had on my test paypal account. once i removed the extra text from the zip code it worked.

The way to fix it is to change the file classes/address.php so that the zip code lenght is bigger than before. by default it's only 12 chars. i changed it to 32  i think it should be enough.
