I currently have Gaea WP theme 2.3.1 running for essla.org. They want to change the registration button link, on this page https://essla.org/?event=welcome-back-dinner-jimbos&event_date=2018-06-03, to go to a different page other than their PayPal.
They have a new processor. Can we keep the registration button and update that link to go to: http://shopping.na2.netsuite.com/s.nl/c.4539183/sc.26/.f
How would I changes this? Thank for your assistance!
