Not Sorting on the frontend

Hello everyone.

I have been issues with sorting my BBpress forum topic on the front end.

I arranged it in the Back-end using the drag and drop features but yet it didn’t reflect on the front-end.

So i tried to use a custom function i got from one of the threads.

Here is the code i used.

//* Change sort order of Topics within a specified bbpress forum
function my_custom_display_topic_index_query ($args) {
$thisforumid = bbp_get_forum_id();

if($thisforumid == 43135) {
$args[‘orderby’] = ‘date’;
$args[‘order’] = ‘ASC’;
}

return $args;
}
add_filter(‘bbp_before_has_topics_parse_args’, ‘my_custom_display_topic_index_query ‘ );

and i got this error

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function ‘my_custom_display_topic_index_query ‘ not found or invalid function name in /home/flexol5/public_html/wp-includes/plugin.php on line 235

Warning: array_merge(): Argument #2 is not an array in /home/flexol5/public_html/wp-content/plugins/bbpress/includes/common/functions.php on line 1419

I don’t know what i did wrong or maybe the coding structure of bbpress as changed. I would like someone to help with a way to arrange a specific forum topic in ascending order.

Thanks
