When using the robots meta management console, it requests the following file from the server:
/wp-includes/images/rss.png
However, this file does not exist.
The referrer is:
http://www.mysite.com/wp/wp-content/plugins/robots-meta/yst_plugin_tools.css?ver=2.9.1
I hope this is helpful in resolving the problem.
Best wishes
