Hey, Aaron thanks for the great plugin.
I'm having an issue on a site where if I change a setting and save it, say the number of tweets displayed, the widget works for one refresh. After refreshing the first time, the "No Tweets Available" message is all that's displayed.
I tried looking into your suggestions here: http://wordpress.org/support/topic/widget-doesnt-show-up-on-the-page?replies=23
Any other advice would be greatly appreciated. Thanks!
