mod_rewrite problem

I have a problem with mod_rewrite. When I click on a permalink to a single post, it shows the archive (all postst) for 2004.
Example: https://www.iblog.dk/nldk/2004/09/25/shit
shows all the posts for 2004.
I am using the following mod_rewrite rules :
RewriteEngine On
RewriteBase /nldk/
RewriteRule ^category/?(.*) /nldk/index.php?category_name=$1 [QSA]
RewriteRule ^([0-9]{4})/?([0-9]{1,2})?/?([0-9]{1,2})?/?([_0-9a-z-]+)?/?([0-9]+)?/?$ /nldk/index.php?year=$1&monthnum=$2&day=$3&name=$4&page=$5 [QSA]
(I have currently disabled the nice permalinks option, but my .htaccess file does contain the rules, so typing the
https://www.iblog.dk/nldk/2004/09/25/shit in my browser should bring up the single post).
Should I change something in my index.php to make it work ? I am a mod_rewrite and WordPress newbie so bear over with me if this is a stupid question. ??
