I got it to work. I had both a .txt version and a .php (webpage) version of my RSS archive feed saved on my hard drive. In the WP dashboard where you can import, I chose Movable Type and Typepad, chose my .php file, and it worked. Saw that on another forum somewhere so I thought I’d give it a try. Why no one on here will tell you about this workaround, I have no clue, but I just wasted a week trying to figure it out!
I’m having the same problem. My blog was run on Expression Engine. I loaded the RSS feed, viewed the source and saved it as a text file, as per instructions I’ve seen in several places.
I’ve tried several times to use the import tool from the dashboard, and it always says “All Done, Have Fun” but nothing is added. I have archives dating back to 2002 that I’d really like to keep. Anyone??
