Hi, we have a wordpress mu installation here and I think we detected some problem (maybe a bug) in the software. The problem happens when I edit the general options for a blog with the global mu admin logged. When this happens, every single post page appears as 404. When I edit the blog again, but in the blog's administration (/test-blog/wp-admin/ instead of /wp-admin/) the issue is fixed.
It's very easy to reproduce, here are the steps from scratch:
1. Download latest version of Wordpress MU (2.7.1.1)
2. Uncompress and install normally.
3. Enter the admin page (http://example.com/wp-admin/)
4. On the menu, click "Site Admin" -> "Blogs" and create a new test blog (Example: example.com/blogtest).
5. Visit de blog and click on Hello World post created automatically. The post will appear normally.
6. Go back to the admin page (http://example.com/wp-admin/), then click "Site Admin" -> "Blogs" and click on Edit when it highlights.
7. Do anything on this page, like clicking on "Update Options" on the Blog Users box on the right.
8. From now on, every single post page now appear as 404 not found, including the Hello World Post.
To fix this:
1. Instead of entering the global admin page, enter in the blog admin page: http://example.com/blogtest/wp-admin/.
2. Update any options and it will work again.
We have instructed everyone to always use the individual blog admin page, but we all know that sometimes people make mistakes :) Maybe this is really a bug and can be fixed?
Thanks and I'll be glad to provide any information and help if needed.
