Thank you, that has helped with the processing now directing to the bank payment form.
We are still having the other issues since upgrading Joomla though. In the admin screen just for Payment form, none of the save or apply etc buttons are working (in firefox & IE yet all other save buttons in admin screens are fine) so I cannot change any of the settings. Sometimes the save works on the very first time but then the url just shows as
flighttest.co.nz/administrator/index.php...=show_configuration#
(note the hash on the end) but nothing happens and details are not saved.
Also since these issues emails are not being sent neither are payment records being saved in Payments Management screen.
So basically my client is finding this no longer a working payments system.
Please please can you help!
