There is a huge bug something between google chrome browser or wordpress.com god knows.I even can’t say which type of bug exactly this is that you can’t able to login to your wordpress.com blog even if you have correct username and password.You even can’t recover your wordpress.com blog account.I had face the same problem with one of my blog.Certainly one day I see I get logged out of my wordpress.com blog.When I try to login it show no such email and user.When I try to reset my password, it say unable to reset password.

1. Whenever i try to login to my wordpress blog  it say no such login.When i try to reset password its say unable to reset password.
   I’m sorry, but we weren’t able to find a user with that login information.
   What should I do now?
   Double-check your spelling.
   Trying entering another email address you can access into the password reset form.
   Confirm you have a WordPress.com account and not WordPress.org.
   Check your WordPress.com registration email for the correct login.
   Did you change your registered email address? Use the new address.
   Help!
   Still having problems? Try our account recovery form and we’ll do our best to get you running again.

   When i try account recovery form,it does nothing and keep showing same error.

  

After a lot of googling I find that its happening with a lot of people.Then I have tried it in different browser other than google chrome.

Thank GOD finally I  login!

The solution of this problem is just use any other browser except google chrome.

Once again I repeat my sentence, If you are not able to login your wordpress.com blog or your blog on wordpress don’t be panic.The easiest solution and the only solution of this problem is just use any other browser except chrome.And don’t be afraid of any kind of hacking.I think its a bug in chrome browser.Wordpress must have to think about this and solve this problem as soon as possible because only god know how many users are using chrome.
