I have tested the api twitter with at least four solutions (one of them ever worked before, months ago) in PHP, and getting the same error: "401 Not Authorized".
Is there any "novelty", any prior authorization to be given to the application? There are others with the same problem? Someone trying anything new in PHP and working well? -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
