Great to hear it works now! I suspect this broke do to the update to WP 4.4. WP has been tightening up the code that processes shortcodes so they are a little less tolerant of errors for the sake of security. My guess you may have something in the shortcode that was breaking. Most often this occurs from copy/pasting shortcodes and their options from a web page.
