Okay, so apparently my WP permalinks decided to randomly cut out on me.
I didn't notice until today, but they've been broken since Saturday. I have the "Custom" option selected, and my permalinks currently are:
They were working fine, and then all of a sudden something weird happened. I tried rebuilding the structure, and it didn't help. I tried changing the permalink structure, and all of the "default" structures worked fine! Then, I changed back to the custom ones and I'm getting a 404.
I tried restoring from an old backup, but it didn't help. All of my posts, RSS feeds, etc. are still broken.
You can see what's going on at http://the-madness.net
Does anybody know what's going on?
