Third party plug-in yes but never encountered this issue before with any other themes and the same plugin (Enfold, Woodmart) so just querying whether the theme could in some way be affecting the outcome?
Error The supplied variables are not according to specification:
amount : amount is required
item_name : item_name is required
merchant_id : merchant_id is required
merchant_key : merchant_key is required
I have entered all the Payfast plugin requires: merchant ID, key, passphrase yet this issue persists. I have also opened a support ticket with Payfast themselves.
Any idea what could be causing this? Theme related?
