I'm trying to archive my tweets in Wordpress and display recent ones in my sidebar. I've installed the Twitter Tools plugin, configured it, and added its widget to my sidebar. Twitter Tools is creating blog posts for each of my tweets, so I know it is authorized by Twitter successully. However, the sidebar widget just displays "No tweets available at the moment."
I've tried the procedure described here to uninstall and reinstall Twitter Tools to no avail.
I'm also using the Ultimate Category Excluder plugin to exclude the tweet posts from my feed and homepage. I'm worried that might be the problem but others seem to be using this setup successfully. Any ideas?
