S2 member - custom thank you page blanc page

Hello,

i follow the instructions to make my own thank you page and paste the code in to my
clickbank product. After making a testpruchase the thank you page show, but the page is blank.
Normally on the site i text and a picture designed with a page builder.
What can i do ?

Have you inspected the page and/or checked your debug.log and PHP error logs to see if there are any error messages?

On the problem page, press {F12} and then click the Console tab. If there are any JavaScript errors they will be displayed here. You’ll need to check the error logs for any WordPress or PHP errors.
