 * Hi,
 * After moving the site to a server that uses php 8 the plugin is throwing an error
   when WordPress sends an email. I found this website [https://plugintests.com/plugins/wporg/ubilop/latest](https://plugintests.com/plugins/wporg/ubilop/latest)
   talking about this error. This is the error:
 * `2023/05/25 14:25:21 **[error]** 8012#8012: *2552 FastCGI sent in stderr: "PHP
   message: PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument#
   1 ($callback) must be a valid callback, class FACT_Admin does not have a method"
   phpmailer_send" in /www/divuit_229/public/wp-includes/class-wp-hook.php:308`
   
   Can you help?
 * Thanks
