I thought I did everything right when migrating an existing multi-step WordPress install over to another server for use as a development server. (ref. this: http://codex.wordpress.org/Moving_WordPress)
I compressed all the wp files to preserve their permissions and used the special search and replace tool (over here: http://interconnectit.com/products/search-and-replace-for-wordpress-databases/) to change the domain name in the db (which is the only thing that changed, everything should be exactly the same as the production site).
The main domain works and I can log in and get to the admin page. But for all the sites on my multi-site (which are configured as subfolders), it says for each one that:
Not Found The requested URL /<subfolder> was not found on this server. Apache/2.2.17
All the files are there in blogs.dir and their permissions are 775, so they should be readable found.
What else could I have done wrong?
