Hi,

It turned out the problem is in the way wordpress analyses the url. It is found in rewrite.php:

/**
670	         * Rewrite tags that can be used in permalink structures.
671	         *
672	         * These are translated into the regular expressions stored in
673	         * {@link WP_Rewrite::$rewritereplace} and are rewritten to the
674	         * query variables listed in {@link WP_Rewrite::$queryreplace}.
675	         *
676	         * Additional tags can be added with {@link add_rewrite_tag()}.
677	         *
678	         * @since 1.5.0
679	         * @access private
680	         * @var array
681	         */
682	        var $rewritecode = array(
683	                '%year%',
684	                '%monthnum%',
685	                '%day%',
686	                '%hour%',
687	                '%minute%',
688	                '%second%',
689	                '%postname%',
690	                '%post_id%',
691	                '%author%',
692	                '%pagename%',
693	                '%search%'
694	        );
695
696	        /**
697	         * Regular expressions to be substituted into rewrite rules in place
698	         * of rewrite tags, see {@link WP_Rewrite::$rewritecode}.
699	         *
700	         * @since 1.5.0
701	         * @access private
702	         * @var array
703	         */
704	        var $rewritereplace = array(
705	                '([0-9]{4})',
706	                '([0-9]{1,2})',
707	                '([0-9]{1,2})',
708	                '([0-9]{1,2})',
709	                '([0-9]{1,2})',
710	                '([0-9]{1,2})',
711	                '([^/]+)',
712	                '([0-9]+)',
713	                '([^/]+)',
714	                '([^/]+?)',
715	                '(.+)'
716	        );

as you can see any url with four numbers will be taken as a year(first lines), I just had to redefine $rewritereplace in my functions.php and flush the rules. I just replaced the first line ‘([0-9]{4})’, by ‘([0-9]{8})’, but you can replace it with anything.

don’t edit the wordpress files directly though.

Good luck
