This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.




Go to for the
explanation, thanks!

“Decategorizer” will remove the category base from your category
links, and turn your category URLs from something like
“http://yourdomain/category/news/” to “http://yourdomain/news/”.


301 redirection for old category links added automatically;
works with most permalink structures (please e-mail me or leave
a comment on plugin’s site if it doesn’t work for you);
you can safely use variables in your category URLs
sitemap plugins compatible;
it works with multiple subcategory links

“Decategorizer” needs John Godley’s
plugin to work and it will disable itself if Redirection is
not installed.
Redirection version 2.x. is recommended (Last tested with v2.1.9)

More info

To see the end result before you decide to install, please
visit and
browse around. You’ll notice that no url contains “category” and still
everything works just fine.

I don’t think I’ve ever written a readme before. Is it full of
spelling and grammar errors? Too long? I suck at explaining how things
work? Drop me an e-mail if something’s bugging you about this text ๐Ÿ™‚

Plans for the next version?

(modified on February 10th 2009 at 11:36PM)

Make it a “Redirection” extending class – does that make any sense?

Or maybe move from “Redirection” completely and just write the values
to the .htaccess file?

Leave a comment here (WordPress forums) or on my site, or send me an
e-mail if you would like to see something added to the plugin.

Thanks for reading this ๐Ÿ™‚


  1. Place the whole ‘decategorizer’ folder into your wordpress’
    installation folder, under ‘wp-content\plugins’.
  2. Go to WordPress administration->plugins page and make sure that
    the plugin’s name (Decategorizer) is on the list, but do not
    activate it just yet.
  3. Install Urban Giraffe’s Redirection plugin the same way,
    if you haven’t already done so.
  4. Activate ‘Redirection’ plugin.
  5. If you haven’t had Redirection installed and used before now,
    go to Redirection plugin’s options page so its database tables
    can be created.
  6. Go back to the plugin management page and activate Decategorizer.
  7. You’re done.

  • february 13th 2009
  • changed redirection form from /cat_name/$ to
    ^/(optional subfolder install)/cat_name/$, so if the install is in a
    subfolder (eg., that subfolder is now
    included in all redirections, just to make it failsafe.

  • Redirections are now added when the plugin is activated, and on a
    few other occasions (see bottom of plugin file for all the hooks).
  • Plugin no longer runs on each and every pageload. Hooray ๐Ÿ™‚


  • plugin now checks if redirection tables exist (d’oh) before
    starting to work. It also checks whether adding redirections is
    actually needed (if you have no child categories, for example).
    -> removed in 0.5 for compatibility reasons (‘/%postname%’ permalinks).


  • added automatic creation of redirection rules.
    PLEASE NOTE: Although I’ve been testing the plugin for the past
    two hours, do try it at home first.
    REMINDER TO SELF: addslashes(), INSERT, save your sanity…


  • instead of setting back category_base to its default value,
    the current value is used, so one’s permalinks don’t get broken if
    they decide to deactivate the plugin. Sorry for that, current users :/
    Please check your ‘category_base’ value.


  • added the filter to ‘category_link’ as well. No more
    “/category/” in links when using “Google XML Sitemaps” and “Dagon
    Design Sitemap Generator” plugins ๐Ÿ™‚
