I have been trying to fix this problem all day with no luck, I have disabled all plugins and read all the similar post in this forum.
My RSS Feed returns a 404 error page not found
when checking on feed validation http://feed2.w3.org/check.cgi?url=http%3A//mrstextiles.com/%3Ffeed%3Drss2 it says <title></title> should not be blank so I added a title and tried the feed and it still did not work. It also states something about object tag which is a link to a youtube embedded video so I deleted the video and the feed still returned the error message.
So i figured it was not the problem so deleted my title and re added the video.
