blank page after form submit in advanced custom field plugin wordpress

I am using active custom fields plugin to display and submit form in frontend inside buddypress groups page.

Form is submitted and record is entered successfully but a blank page is displayed after form submit. Only the header section of the page is displayed.

I have tried using acf/save_post and acf/pre_save_post hooks to redirect page but none of them seems to work.

Here is my code:

$options = array(
'post_id'       => 'new_post',
'post_title'    => true,
'new_post'      => array(
    'post_type'     => 'event',
    'post_status'       => 'publish'
),
'submit_value'      => 'Create New Event'
);

acf_form($options);

Thanks in advance.
