Plugin broken after last update

Looks like this plugin is not working, displaying an error in both the settings page, and the posts where the list should appear. This error is returned in both locations:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in /home4/dnamped/public_html/sacramentodiscgolf/wp-includes/class-wp-hook.php on line 298

Here’s the block of code with the referenced line in bold:

// Avoid the array_slice if possible.
if ( $the_['accepted_args'] == 0 ) {
	$value = call_user_func_array( $the_['function'], array() );
} elseif ( $the_['accepted_args'] >= $num_args ) {
	$value = call_user_func_array( $the_['function'], $args );
} else {
	$value = call_user_func_array( $the_['function'], array_slice( $args, 0, (int)$the_['accepted_args'] ) );
}

Line 298 is the one with $args declared

Any assistance would be appreciated, thanks!
