Admin Login Error message

My site has been working normally and this morning when I go to login to my admin i get:

Parse error: syntax error, unexpected ‘public’ (T_PUBLIC) in /home/ezgro/public_html/wp/wp-admin/includes/class-wp-list-table.php on line 636

The site is still working fine but I cant login to the admin. What would have caused this?

I have gone into the code of the file class-wp-list-table.php and here is the code where the error is happining.

/**
* Make private properties readable for backwards compatibility.
*
* @since 4.0.0
* @access public
*
* @param string $name Property to get.
* @return mixed Property.
*/
public function __get( $name ) {
return $this->$name;
}

Here is the link to my admin login:
