FkingThis plug-in is having series after effects on your site (and possibly your rankings) even long after deleting it. It does some nasty caching and URL redirects that make your site show 10s of soft 404 errors in Google Webmaster Tools, even months after you have uninstalled it.
For example for me it forwards all the previosly existed URLs to the homepage instead of showing proper 404 page and 404 server response.
Did someone find a way to sucessfully recover and cover all it's tracks?
