The latest version of Twitter Tools uses OAuth for authentication. This worked fine for me on WordPress 2.9.2. When I upgraded to 3.0.1, Twitter Tools stopped working at my blog http://www.shekhargovindarajan.com. Note that the version of Twitter Tools I’m using is 2.4.
Next, I followed the steps mentioned at http://www.shekhargovindarajan.com/wordpress/a-perfect-integration-of-wordpress-and-twitter/ - refer to Update (November 15, 2009). But this time, I faced a different issue.
The authentication (the first step before setting up the plugin) kept failing saying “Authentication Failed. Please check your credentials and make sure Twitter is up and running”.
After hours of troubleshooting at the code level, coincidently I happened to check my server’s time (system time). It was lagging behind by several minutes. Updated my server’s time (via ntpdate ntp.ubuntu.com) and voila! the authentication worked. The sidebar is showing the latest tweets now.
Yet to see if the daily digests will start shooting up again.
