I’m having a similar problem. I had my blog on wordpress.com, but finally downloaded wordpress on my own site, and installed a theme. I exported my blog from wordpress.com and imported into my site (nicolekrug.com) all the posts and content are showing up in my admin panel, and my blog digest shows up (nicolekrug.com/wordpress) so it appears that the import worked; however, when I click “read more” I get nothing.
I even tried creating a new post and it went to the digest page, but I can’t read more. I can click through the tags and even see comments, but any “read more” gives me a page not found.
I just tried adding the code suggested at the link above, to no avail.
Any assistance would be greatly appreciated!
