Answer 1

If you authorized your application to access your Twitter account when the application was set in "read only access" mode and you get the "Read-only application cannot POST" error after changing the application settings to be "read and write access" then you have to revoke access to the application on https://twitter.com/settings/connections and then reauthorize it. The "read only" access_token tends to be sticky until you revoke it.

Answer 2

Dunno what the problem was, but I deleted my Application registration on Twitter (You have to register apps in Twitter to get OAuth keys etc.), and then recreated it. Now it works fine. Weird, probably a problem with Twitter screwing up.

I'm also using Tweetsharp (http://tweetsharp.com/), highly recommend it, it's got a nice fluent API. Note: switching over to Tweetsharp wasn't the fix, I had already switched over and had the same problem until I delete and recreated app registration on Twitter.

Answer 3

• Go to http://www.twitter.com/oauth_clients
• Select your App.
• Edit Application Setting.
• Set Default Access type to Read & Write.
• Save & Run.

Hope this helps.

plus also see if your system's CLOCK is synched with internet; on windows you can do it by adjusting date time settings

because if you CLOCK is not synched you will get 401 unauthorized exception; best of luck cheers
