Website not working: Error: Parse error: syntax error, unexpected '

Please help. My website at highlineonline.ca is not working. I was trying to update a plugin and now get this error:

Parse error: syntax error, unexpected ‘<‘ in /home/highline/HighlineOnline.ca/wp-content/plugins/jetpack/modules/comments.php on line 28

What should I do?

This is the code on the page it now won’t let me navigate away from without the error:

<?php

/**
* Module Name: Jetpack Comments
* Module Description: A new comment system that has integrated social media login options.
* First Introduced: 1.4
* Sort Order: 2
*/

require dirname( __FILE__ ) . ‘/comments/comments.php’;

if ( is_admin() ) {
require dirname( __FILE__ ) . ‘/comments/admin.php’;
}

function jetpack_comments_load() {
Jetpack::enable_module_configurable( __FILE__ );
Jetpack::module_configuration_load( __FILE__, ‘jetpack_comments_configuration_load’ );
}

function jetpack_comments_configuration_load() {
wp_safe_redirect( admin_url( ‘options-discussion.php#jetpack-comments-settings’ ) );
exit;
}
add_action( ‘jetpack_modules_loaded’, ‘jetpack_comments_load’ );
