Page not found messages after settings copied between Fantastico installations

So, here’s the scenario. I have a WordPress blog. It’s great. But it’s hidden deep within my domain name. So I need to build a website around it. With my blog, I have found that blogging is a great, easily customizable way to publsh on the Internet. So rather than break out my HTML editor and start hacking away at DOCTYPES and <meta> refreshes, I decided to make another blog to use for a different section of the site. So I installed WordPress 2.8.6 with Fantastico, then upgraded to 2.9.1 (exactly as I did with the old blog).

But, of course, I want it all to look pretty much the same everywhere. However, it took me 4 days to get my first blog’s settings the way I want them, and I can think of plenty better things that I can do in that time while setting up my new blog.

So I went the “easy” way: I went into phpMyAdmin, exported my old blog’s database, and loaded it up in WordPad. I took out everything but the SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO"; line, the CREATE TABLE 'wp_options'(... thingy, and the INSERT INTO 'wp_options' section, and also changed the ‘site_url’, ‘blog_name’, ‘blog_description’, and ‘admin_email’ values (I use different emails for each of them.)

I saved the file to my desktop, then DROPped the wp_options table in phpMyAdmin. I went to the ‘Import’ tab, uploaded my file, and it ran the 3 queries, thus creating the table and my settings. I copied over the plugins and themes directories to my new blog’s wp_content directory, and the blog’s homepage appeared how it should – the ‘Hello World’ post was in the theme used with my old blog, with all of its settings and such.

So, everything should work, right?
No.

When I go to the /hello-world permanent link, it brings up the WordPress standard ‘Not Found’ page, with my old blog’s title, description, and even tag cloud, though the URL is correct.

Just how is that possible, and how do I fix it?
