psostre,
I am having the same issues as you (and as most everyone else here at some point or another). karlalopez, can you fill us in?
One thing I notice is that under FTP server in my blogger settings, I can only type in mydomain.com, as opposed to https://ftp.mydomain.com, if I want blogger to republish successfully. I suspect that wordpress’s import-blogger tool reads the ftp name from this, and it it sees mydomain.com instead of https://ftp.mydomain.com, it does not compute.
beyond that, I am at a loss. also, i noticed that my archive files went from being .htmls to .phps, but that only two of my many actual post files converted. were they all supposed to convert? if so, could I do this manually?
