[Plugin: Rotating Tweets widget and shortcode] Fatal error on line 232

This error was happening (on a different line, I can’t remember which) before the update that came out today so I went looking for something else, but didn’t find anything yet. So when I saw this update, thought I’d try again, but still getting this error:

Fatal error: Cannot use string offset as an array in /home/mydomain/public_html/wp-content/plugins/rotatingtweets/rotatingtweets.php on line 232
