I am a big fan of YARPP and using it for almost every project. Recently I came to the need to display related posts for Custom Post Types. I appreciate that you have support for this but I am not able to display the related posts for the "download" custom post type of EasyDigitalDownloads.
The EDD plugin already registered the custom post type so I tried to use add_post_type_support in order to add the support for yarpp_support, but it displays "No related posts" all the time.
I also tried different yarpp_related parameters, my latest attempt was this http://pastebin.com/hxBUjKQN without any luck. I assumed that the arguments in this function overrides any other post type setting or should yarpp_support being registered even if I use the custom arguments?
I really need an advice on this and it will be strongly appreciated.
