My website is http://www.MyOpenTheatre.com. I previously used normal posts permalinks like http://www.myopentheatre.com/?p=123 after changed to http://www.myopentheatre.com/2009/03/27/sample-post/ and after /%category%/%postname%/ and now finally as /%category%/%postname%.html After that I used permalink redirection and tried to change all posts url as /%category%/%postname%.html. But I got into serious problems. Try visiting http://www.myopentheatre.com/2009/killer-nurse/ . Its taking to completely different site !!!!!!!! And URL's Not Followed as in Google Webmaster is http://www.myopentheatre.com/movies/ http://www.myopentheatre.com/movies says "Redirect error" And look at this http://www.myopentheatre.com/category/video/page/86/ Wherever I am getting 404 Error its going to www.video.com
