I want to add some text at the top of the checkout page telling people not to click their browser’s back button because this can tie up a spot and make an event look sold out when it isn’t really. I tried editing the checkout page directly but it seems to set focus on the form so the text I added at the top isn’t visible unless someone would scroll up. I understand I can add some more text here: “In order to process your registration, we ask you to provide the following information. Please note that all fields marked with an asterisk (*) are required.” I have a site specific plugin but couldn’t figure out how to add the text translation there.
