I set up a Thank you code with some basic html and CSS (message, invoice in a table, etc).
We then edited this code. I am 100% sure I deleted the original code and pasted in the new, edited code.
Whenever we test checking out, however, we see BOTH the original checkout code and then the edited code, instead of just the latter.
This looks terrible and makes no sense to customers. I have tried saving new versions of the thank you page html repeatedly, to no avail. How can we permanently clear out the first version of our html on the thank you page?
