Disable all plugins, and reactivate one by one and try to burn your rss until you find which plugin might cause that problem
Are you providing the correct details to feedburner? you should enter the valid URL of your blog to feedburner in order to burn as feed. Is it a new blog with no post? There must be atleast one post. It is also suggested to upgrade to latest version of wordpress if you are not already using the one. check the link if it helps http://wordpress.org/support/topic/308112
You only need to enter you website/blog URL to feedburer input box, where it says: Burn a feed right this instant. Type your blog or feed address here: Type http://www.mywatchmovie.com and hit 'next' button.
When i do this, i got this error and when i try to confirm its validity, i got this - http://feedvalidator.org/check.cgi?url=http://www.mywatchmovie.com/feed/atom/
It's working find here at my end.. Just repeat the steps again.. Also, its validated here: http://feedvalidator.org/check.cgi?u...feed/atom/
