I’m actually having the exact same problem.
I was originally attempting to import to WordPress from Diaryland, so I used the Rhino exporter to get it to Movable Type format. And now I have this perfectly fine MT format export file… and I’ve been able to successfully import it to my WordPress.COM blog, but not WordPress on my server.
It imports perfectly, then tells me to go “have fun”, but when I go to the Manage tab, it lists the months (back to 2001), but won’t show the entries. Apparently, I still have no entries.
Anyone have any ideas? This is getting frustrating.
