Folks,
The Theme Horse Web Site is kaput (I hope this doesn't mean that you've suddenly gone titsup).
I own the Pro version of this theme, and I am getting dozens of these in my dashboard:
Warning: simplexml_load_string(): Entity: line 1: parser error : Space required after the Public Identifier in <PATH>/wp-content/themes/clean-retina-pro/library/functions/update_notifier.php on line 123
I assume this is because the server is dead, so the updater gets a 404 page or something.
