I use XML-RPC for posting to blog from C#. I use All-In-One SEO Pack and used to insert custom fields '_aioseop_title' '_aioseop_description' and '_aioseop_keywords' from it (This is what AIO uses).
However after upgrading the 3.2 it no longer inserts these. It does insert normal ones.
Is there any change for custom fields or I am missing something? If someone could help / share thoughts?
