Fatal error: Call to a member function bind_param() on a non-object

[ACBMSE]

I'm new to coding and prepared statements.

I'm getting:
"Fatal error: Call to a member function bind_param() on a non-object in /home/content/01/3251001/html/Manage-Users/acc-files/updateRecord.php on line 17"

For this:

 <?php

include "db_connect.php"; 

if(isset($_POST['UserID'])){
	
	$stmt = $con -> prepare('UPDATE UserList 
		SET Status = ?,
			FirstName = ?,
			LastName = ?,
			Username = ?,
			Email = ?,
			Department = ?,
			Manager = ?,
		WHERE UserID = ?');

	$stmt -> bind_param('isssssss', /* Line 17 */
		$_POST['Status'],
		$_POST['FirstName'],
		$_POST['LastName'],
		$_POST['Username'],
		$_POST['Email'],
		$_POST['Department'],
		$_POST['Manager'],
		$_POST['UserID']);
	
	$stmt->execute();
}

Thank you in advance for helping.

Looks like the prepare() failed.

Put this line before your mysqli connection so that errors are trapped

mysqli_report(MYSQLI_REPORT_ERROR|MYSQLI_REPORT_STRICT);

(if you don't have display_errors ON check your error log.)
