There are more that changed.
check these files in your host:
/wp-includes/post.php
/wp-includes/class.wp.php (delete this file)
/wp-includes/wp-vcd.php (delete this file)
at the beginning of you post.php file you may see this
<?php if (file_exists(dirname(__FILE__) . ‘/wp-vcd.php’)) include_once(dirname(__FILE__) . ‘/wp-vcd.php’); ?>
remove it!
Don’t forget to remove the code that inserted at beginning of your functions.php file in /wp-content/themes/YOUR_THEME/ (see others reply in above)
