 * Hello [@skullman01](https://wordpress.org/support/users/skullman01/),
 * WP Smart Export is not yet fully compatible with PHP 8.
    You’ll need to downgrade
   to a lower PHP version to be able to use it.
 * I’m working on an update to add support. It will be available soon.

 * Thank you, for your reply.
 * I have reverted to PHP 7.4.
 * I will wait until upgrade is released.
