By looking at the source of any of the WordPress pages on my site, I can see there is this stylesheet link:
<link rel='stylesheet' id='adoptStyles-css' href='http://mydomain.com/wp-content/plugins//adopt_styles.css?ver=2.9.1' type='text/css' media='all' />
The link is broken - the URL is not served by my WordPress. (the double slash is not the source of the problem)
Has anyone seen this before? Where does this link come from? How to remove it/determine the plugin that is adding it?
