SyntaxError: Unexpected token ILLEGAL

If you get a SyntaxError: Unexpected token ILLEGAL error in your console when clicking on the Generate button w/ version 3.3.4, it’s because you have WP_DEBUG on and the plugin is using a deprecated function. Change js_escape on line 122 of auto-post-thumbnail.php to esc_js.
