Archive on this site works fine by date, but by category or tag it’s broken. I just get the frontpage. It used to work, and sorry to say, I’m not sure when the problem started. No clue there.

Plugins running on this site can be found here, and WP version is
3.1-beta1-16590.

Things I have tried:

  • Disabled WP Super Cache. Still running with it disabled. Hard to do but everything in order to find this problem…
  • Disabled Redirection. Still running with it disabled. I miss it.
  • Cleared and recreated /.htaccess from the permalink settings page. On the same page I have tried other, longer, settings than c for category and t for tags. Same problem. They get written as they should but when I click them I still end up on the frontpage.
  • Changed to Twenty ten and others. And back again. Same problem with every theme

And probably more. I have searched high and low and talked to a lot of WP experts. No luck. I need some advice.

Pretty, pretty please – with cream on the top. Please help!

You asked for my .htaccess. Here it is, all cleaned up.

# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress
