Yes, I do use WP Travel Utilities. I already had the Thank You page set there.
However, now that I am using your PayPal Express plug-in when I went to generate a “Client ID” I also set a URL redirect in my PayPal developer settings. Should I not have set that redirect in Paypal? Are you telling me to leave the redirect in my Paypal developer settings empty?
Will the Paypal redirect I set override the redirect set by the Travel Utilities plug-in?
Also, in your screenshot the field description for the Thank You page is wrong.
Description Error: Thank You Page – “Choose the page to use as checkout page for booking”
This description needs to say something like: “Choose the page that travelers will be redirected to after booking.”
