Ok. After poking around a bit found that when the page loads on the server an error was being logged:
PHP Fatal error: Call to undefined function curl_init() in <snip> /wp-content/plugins/ai-twitter-feeds/twitteroauth/twitteroauth.php on line 195

Apparently, this server was missing the php curl extension.

On Debian this was remedied with:
apt-get install php5-curl

Thanks for a good looking plugin.
