when you mark the option to import media also it
appears to be doinf something, lists media files etc and at the end it just stops, but nothing has been imported, no posts, pages nothing..
only the media library is available.
when you again try without media import it does import posts, however, all feature image settings are lost.
I have posts in two languages, and I could choose the language, but it is all mixed up and the connection links between translations are lost.
It is a mess.
