You (or your developer/hosting company) need to remove those PHP constants that prevent PHP processing.
Have you solved the issue?
Great 🙂

Thank you!
I was having the same problem. Updating the wp-config.php file as suggested on https://adinserter.pro/documentation/code-editing#php-code solved it for me. Thanks!
