fatal error

HI i keep getting this fatal error 

PHP Fatal error:  Uncaught Error: Call to undefined method mysqli_stmt::get_result() in /home/tradehun/public_html/th/lib/classes/users.php:240

Hey can you please make sure your PHP version is 7.4 or above? 

And also create a file like phpinfo.php

and add following code to check your PHP and MySQLI details. 

<?php
  phpinfo();

it seems like your MysQLI is not working you can check with your web hosting.
