Getting error after transferring Sendy to new host

Hello, I transferred Sendy to a new host. I moved all the Sendy files. Then I moved the SQL Database and updated the Config files.

Thereafter I got a blank screen @ http://faadoodeals.com/sendy/

Now I added a command to check the error : error_reporting(E_ALL); ini_set('display_errors', 1);

Now it is showing me the following error :

Fatal error: Class 'mysqli' not found in /home/faadoodeals/public_html/sendy/includes/functions.php(2) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code on line 1

Please find me a solution.
