Disable taxonomy pages
If you don't need taxonomy you can always just disable the module.

If you still need the functionality but don't want the display pages to exist I guess you could implement hook_menu_alter() to remove them from the registry:

function MYMODULE_menu_alter(&amp;$items) {
  unset($items['taxonomy/term/%taxonomy_term']);
  unset($items['taxonomy/term/%taxonomy_term/view']);
  unset($items['taxonomy/term/%taxonomy_term/feed']); // If you want to hide the feed as well.
}


I'd do some thorough testing after doing that though, I'm not sure if it would have any knock-on effects. Also if you're using the default taxonomy View for your taxonomy pages you'll obviously need to disable that as well.
