I run a not-for-profit staff yoga club at the University where I work and I want to use Paypal buttons on our webpage to take club payments.
I have set up a button in Paypal with an inventory limit, generated the code and created buttons with links in my website. The button looks fine and has a live link with the correct product ID in it. However, if I click on the button, instead of the check-out page it takes me to a generic Paypal error page saying "Things don't appear to be working at the moment. Please try again later."
I can't understand what I've done wrong. Can anyone help?
