Under wp-content, create a new sub-directory called mu-plugins. Drop the .php file underneath it and you are all set!

thanks so much Eric :)

Eri, one more thing as I can comment on the forum, not a paid member
Does it only work with Pro version of the Forminator plugin?
As nothing happens
I changed lines 146, 147 and nothing else:

$upload_dir_url = WP_CONTENT_URL . "/uploads/freetry/{$this->form_id}/{$temp_hash}";
$this->upload_dir_path = WP_CONTENT_DIR . "/uploads/freetry/{$this->form_id}/{$temp_hash}";

Just need to know if a Pro version is needed or there is something on my end

Thanks
