I have upgraded from 1.5.2 to 2.0 (and 2.0.2) several times now, without result. Thankfully, my backup was fine, so I was able to restore my blog.
My problem is, that the blog at first glance looks to be working fine. I can see the blog home page and can click any link to a category, archive or single entry. But when that page is shown, it always is the home page again.
I think that it has to do with permalinks not working. I get a new generated default .htaccess file. But my gut feeling is, that WP is unable to handle the permalinks. I use the date/slug option, btw.
Does anyone experience similar problems? Or better, has anyone solved this issue?
Thanks to anyone in advance for the support.
