Update: I work with XML for a living, and figured that I can always wipe this out and start over, so I removed the posts that had already been imported, and left just the remaining ones, from the XML. They imported, though some are showing multiple times, which worries me. It looks like maybe the “duplicate” is just the comments, but I didn’t recall that being the case during the original import.
If it matters, I selected the option to import attachments.
Also, this time, the bottom of the page says “All Done”, which didn’t happen last time. I’m wondering if I closed the page before it was actually finished (even though the page appeared to be done, and wasn’t showing any imports happening). If I have to start over, I’m going to allow more time before I close the page.
I just checked, and all of my posts seem to have imported just fine. I would suggest anyone having this problem first try starting over, and waiting longer during the upload period.
I’m having this problem, as well. The entries are in the XML file I downloaded, and it looks like I’m missing 71 posts, and they’re everything after 5/22/08.
