I created a widget, but when i activate it, i get the following message: "The plugin generated 3 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin."

<?php
/*
Plugin Name: Kamera Widget
Description: kamera
*/
class KameraRa extends WP_Widget {
function __construct() {
parent::__construct(
'KameraRa',
__('Kamera', 'wpb_widget_domain'),
array( 'description' => __( 'Kamera v živo', 'wpb_widget_domain' ), )
);
}
public function widget( $args, $instance ) {
$title = apply_filters( 'widget_title', $instance['title'] );
echo $args['before_widget'];
if ( ! empty( $title ) )
echo $args['before_title'] . $title . $args['after_title'];
echo __( '<a target="_blank" href="http://www.ex.com">
<center><img width="100%" src="http://ex2.com" alt="RTC Kranjska Gora - Kekec"></center>
</a>', 'wpb_widget_domain' );
echo $args['after_widget'];
}
public function form( $instance ) {
if ( isset( $instance[ 'title' ] ) ) {
$title = $instance[ 'title' ];
}
else {
$title = __( 'Snežni park v živo', 'wpb_widget_domain' );
}
?>
<p>
<label for="<?php echo $this->get_field_id( 'title' ); ?>"><?php _e( 'Title:' ); ?></label>
<input class="widefat" id="<?php echo $this->get_field_id( 'title' ); ?>" name="<?php echo $this->get_field_name( 'title' ); ?>" type="text" value="<?php echo esc_attr( $title ); ?>" />
</p>
<?php
}
public function update( $new_instance, $old_instance ) {
$instance = array();
$instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';
return $instance;
}
}
function wpb_load_widget() {
register_widget( 'KameraRa' );
}
add_action( 'widgets_init', 'wpb_load_widget' );
?>
I tried removing all blank spaces around <?php and ?>, but it doesnt help.
What am i doing wrong?
