BuddyPress.org

Everything was working fine, and now it’s not. The error I get in the console is this:

Uncaught Error: cannot call methods on autocomplete prior to initialization; attempted to call method

This seems to be the code causing it:

		jQuery(document).ready(function() {
			var acfb = jQuery("ul.first").autoCompletefb({urlLookup: ajaxurl});

			jQuery('#send_message_form').submit( function() {
				var users = document.getElementById('send-to-usernames').className;
				document.getElementById('send-to-usernames').value = String(users);
			});
		});

I am using wp 3.9 and BP 2.0.1
