My example, i wanted to use /category/postname then in custom structure i typed: /%category%/%postname%/
saved.. and didn’t work.. why?? if i am using that in other blogs.. then i check those… and when i change something in permalinks, those DO tell one needs to add this to the .htaccess file of the site:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
that should make it work with any structure you want for example
/%category%/%postname%/%day%/ or even make one like /ilovepotatochips/%month%/%day%/%postname%/ or anything you like
I hope that helps, i don’t know why version 2.7.1 does NOT tell you that part of the .htaccess
