Since a recent WordPress upgrade, I tried to access my wp-admin panel with the URL I usually use, such as domain.com/wp-admin/ but now I get a 404 error. This is happening on several different installations of WPMU.
Does anyone know why this is happening and how I can fix it? I can't get to the admin panel anymore.
It's not WPMU, it's WordPress MultiSite (yes, it matters - MU means you're using WPMU 2.9.2 or older).
Turn off all your plugins for starters.
And check to make sure you still have an htaccess file.

I fixed it by downloading the latest WordPress and replacing the wp-admin folder, then could get to the admin panel and click on the upgrade notice link.
Previously, I had already tried disabling plugins by renaming the plugin folder, and changing the .htaccess file to a default one from the Codex.
In the version that I had problems with, all the category links had changed to be without "blog" in the URL, like domain.com/category/category-name instead of domain.com/blog/category/category-name. It's now back to normal. I think I did the upgrade around March 27.
Sunds like a corrupted upgrade then. Bummer :(
