WordPress MU

I get a 404 Not Found error when I click on the title of a blog post, as when trying to read it in its entirety.

One blog afflicted is

ablog.freedomblogging.org

Only one blog? Is it all of them or just a select few that are like this?

What does the webserver's error logs report?

One thing to check is to make sure mod_rewrite is active. You'll probably have to get with your host to confirm that.

Mod_rewrite isn't active, or it's not reading the htaccess file.

ask your host.

I just got this too. The blog post was there. Then I went in to enable a theme for that blog alone and it gives Error 404 - Not Found where the blog post should be.

WPMU 2.8.2

Any suggestions?
