404 Errors after copying site and changing wp-config file.

Hello!

I’ve read every forum post I could find as well as the Moving WordPress codex and several other tutorials about creating a copy of my WordPress site for testing purposes. After trying it multiple times, I’m still getting 404 errors every time I try to access a page other than the index.php page.

These are the steps I followed:

1. I downloaded my site files and copied them to the htdocs folder in my Apache installation.
2. I created a new database.
3. I exported the database for my live site.
4. I imported the data from the live site database into the new database.
5. I changed the wp-config file to access the new database, with the new user name, db name, and password, with localhost as the host.
6. I used MySQL workbench to change the _options table, setting the option_value column for “home” and “siteurl” to my new url.
7. For good measure, I also defined WP_HOME and WP_SITEURL in my wp-config.php file to be my new url.
8. I doubled-checked that Settings-General and Settings-Permalinks showed my new url instead of the old one and hit “Save” a few times.
9. I used the Velvet Blues plugin to update as well, just to be sure.

I get 404 errors whenever I access a page other than the home page, and I am unable to view the pages even in preview mode.

I’ve been working on this for days! Please help : )

The original website is http://www.pacificnorthern.com. The copy of the site is http://dev01.pacificnorthern.com. They are not on the same server- the live site is hosted with a hosting service, while the test site is hosted on a computer I have remote access to and is only accessible on our company intranet.

Any help is very much appreciated! Thank you!
