Our plugin makes front-end AJAX requests instead of using admin-ajax.php because we need to render shortcodes (and some don't render in the admin).
In the advanced-cache.php file, a shutdown function is being registered that outputs an HTML comment into our JSON response when WP Super Cache is broken. Could the method of alerting a user to a broken WP Super Cache install be changed (possibly a message on the plugins page) to fix this issue? I have to imagine this could potentially affect others making front-end AJAX requests that expect a JSON response.
Thanks!
