Permalinks with category may give a 404 error if /category/ is not in the URL

[PozHonks]

I use the following permalinks structure: /%category%/%postname% . If someone accesses to this page ​http://www.domain.com/holidays/my-super-summer-time , then in his browser manually erases the postmane to come to this ​http://www.domain.com/holidays/ , there is a 404 error, because it should have been ​http://www.domain.com/category/holidays/ instead.

To solve this, I've personnally created redirect rules in my .htaccess file, but, I think, WP should edit this by itself in order to prevent this error. Here is an example of a redirect rule I use in the .htaccess file:

RedirectMatch permanent ^/holidays/$ http://www.domain.com/category/holidays/

I have a similar problem.

What does not work is any custom permalink which does not start by /index/ or /index.php/.
So if I use /index/%category%/%postname% the permalink is working, I mean that when I click on an article, page, etc. I actually see it.
If I use /%category%/%postname% the permalink is not working. On the front page, the link seems to be correct to a post (<blog URL>/category/article) however if I click on the link I get a HTTP 404 error.

However, in my case, if I replace index or index.php by category, I have also the HTTP 404 error :-(

Note that:
/%category%/%postname% will create a link in the form <blog URL>/mycategory/mypost
whereas
/index/%category%/%postname% will create a link in the form <blog URL>/index/mycategory/mypost

Configuration:

• brand new installation of Wordpress 2.1.2
• Apache/2.2.3 (Ubuntu) mod_python/3.2.10 Python/2.5 PHP/5.2.1

I hope the target milestone will be reconsidered and this issue soon be solved...

This doesnt appear to be an issue on trunk at present

permalinks: /%category%/%postname%/
/uncategorized/test-post/ shows the Post
/uncategorized/ shows Uncategorized archive

I'm assuming this was probably changed with the canonical stuff or something.

jberthon's problem seems to suggest (his|her) problem was Mod_rewrite.
