Transaction error on free subscriptions (Paypal enabled for paid)


We have Paypal set up for taking subscription payments on journals - this is working fine.

However, one subscription is set to be free (i.e. £0.00) - and on attempting to sign up to this, the following error occurs:

Open Journal Systems

A transaction error occurred. Please contact the journal manager for details.

I’m guessing this is because it’s trying to send a zero value order to Paypal?

If so,:

  1. Can this be patched in a future edition
  2. Any ideas where I can put a if ($amount!=“0”) { condition around the routine that calls Paypal in order to allow the subscription to complete?
