 * Hi, I get a critical error when registering users manually, the user gets added
   but it always causes a critical error.
 * Part of the error without the URLs
    Error: An error of type E_ERROR was caused
   in line 404 of the file
 * Error message: Uncaught ArgumentCountError: Too few arguments to function um\
   core\User::on_update_usermeta(), 3 passed in /mnt/data/home/

 * Try to activate PHP error logging and post the `debug.log` file content here 
   in the Forum.

 * Hi [@webb64b](https://wordpress.org/support/users/webb64b/)
 * Thanks for contacting our support.
 * It looks like Fluent CRM is re-creating the action hook `added_user_meta` and
   passes 3 parameters only. They should pass 4 parameters based on this documentation:
   [https://developer.wordpress.org/reference/hooks/added_meta_type_meta/#parameters](https://developer.wordpress.org/reference/hooks/added_meta_type_meta/#parameters)
 * Please contact them regarding this issue and see if they can fix it on their 
   end.
 * Regards,
