CakePHP意外的t_string在一个空行

I am experiencing this error on a CakePHP website:

Parse error: syntax error, unexpected $end in /home3/website/public_html/app/controllers/users_controller.php on line 1010

The thing is there is no code/comment/anything on that line, and the website was working up until an hour ago.

The nearest code to line 1010 is

$user['User']['facebook_locale'] = $facebook->locale;

This error is affecting any page I try and visit, eg domain.com, domain.com/sub/page

Here is the code around the 1010 line mark

$user['User']['facebook_locale'] = $facebook->locale; (line 1007)
// Line 1008
// Line 1009
// Line 1010
$this->User->save($user, false); // Line 1011

I inherited this website so the blank lines were there already.
