Yeah, same problem. Again. This problem exists for months, why isn’t it being patched properly?
At first I thought WP Super Cache was the problem, because the plugin suddely updated when I deactived WP Super Cache. But after that there were no updates any more.
I tested the plugin with all other plugins deactivated: no updates.
I reinstalled the plugin: no updates.
Using the latest version of wordpress and twitter widget pro, theme: child of twenty eleven.
Same problem, not working since 3.2.1. I only see one tweet from several days ago, newer tweets are not displayed.
