Fatal error: Call to undefined method mysqli_stmt::get_result()-Collection of common programming errors

i’m working to a web app, and PHP is my backend language…

until now, i tested the website on localhost, using easyPHP (PHP version 5.4.6)… and everything was good! Today i tried to run the website online (PHP version 5.3.18), and i’ve this error:

Fatal error: Call to undefined method mysqli_stmt::get_result() in etc.

I think this is strange, because the get_result() method should be supported since PHP 5.3.0 (source)

Do you have any ideas how to solve this problem?

Thank you in advance

UPDATE:

i didn’t share any code because it is just fine (it still works on my localhost)… the problem should be on the online environment.

UPDATE 2: I share the section of the phpInfo with the info about mysqli…
