Recently, we upgraded WordPress to 5.2.4 and php to 7.3.10. In doing so, Revive 3.0 stopped working. So, we upgraded Revive to 5.0. Everything looks good and functional. And we're seeing all banners visually under each client in Banner Properties. However, we get white screens when invoking https://ads5.moviemaker.com/revive/www/delivery/afr.php?zoneid=4 or any zone that is occupied. Any thoughts what might be the issue? Thank you.
