Permalink /%category%/%postname%/ fails to generate

[anonymousbugger]

Permalink /%category%/%year%/%monthnum%/%day%/%postname%/ fails. %category% is replaced by none: %year%/%monthnum%/%day%/%postname%/. Error 404 - Not found

The same problen in 1.5.2 Strayhorn.

Problem is in generation, not work.

If I put correct category in url - page opens correctly.

But, what I see: permalinks, that were previously generated correctly, generated in strange way:

Instead of creating link (in title and "more..") to ​http://wwwua.petrenko.com.ua/seen/graffity/chicken-little/ it creates link to ​http://wwwua.petrenko.com.ua//chicken-little/

In permalinks structure - /%category%/%postname%/...

Moreover, long link (​http://wwwua.petrenko.com.ua/seen/graffity/chicken-little/) - works...

So, I experimented about for a while: made couple of fresh installs on different urls on the same server - the same situation - %category% is missing.

I have access to server configuration (VDS). May change of some settings help?

I want to stress: ALL PERMALINKS WORK CORRECTLY IF PROPERLY GENERATED or created (it is not problem in .htaccess rules; apache 2).

Just installed WP2. The same problem.

My new observations.

In file template-functions-links.php
$cats = get_the_category($post->ID); - returns table (array), where categories matching post ID shoild be.

$category = $cats[0]->category_nicename; - should take from this table (array) first match nicename for category.

BUT in fact, it should take instead of [0] (means first row), row with category number. So, I understand, that function function get_the_category($id = true) in template-functions-category.php works incorrectly on some hosts or with some settings, selecting ALL categories, not the one.

I understand, that you are working hard on WP2, but now it is proved to be a bug in WP2 too ;-)

Works for me.
