Fatal error: Call to a member function execute() on a non-object in C:\xampp\htdocs\Panel\admin_config.php on line 44

if ($mySQLcon->connect_errno) {
echo "Failed to connect to MySQL: (" . $mySQLcon->connect_errno . ") " . $mySQLcon->connect_error;
}

$stmt = $mySQLcon->prepare("SELECT `shopstatus`, `shopname`, `wartungsgrund` FROM `" . $table_settings . "`");
$stmt->execute();
$res = $stmt->get_result();
$row = $res->fetch_assoc();

$shopstatus = htmlentities($row['shopstatus']);
$shopname = htmlentities($row['shopname']);
$wartungsgrund = ($row['wartungsgrund']);
als code:

if ($mySQLcon->connect_errno) {		echo "Failed to connect to MySQL: (" . $mySQLcon->connect_errno . ") " . $mySQLcon->connect_error;	}	$stmt = $mySQLcon->prepare("SELECT `shopstatus`, `shopname`, `wartungsgrund` FROM `" . $table_settings . "`");	$stmt->execute();	$res = $stmt->get_result();	$row = $res->fetch_assoc();		$shopstatus = htmlentities($row['shopstatus']);	$shopname = htmlentities($row['shopname']);	$wartungsgrund = ($row['wartungsgrund']);
