   Hello,

   My permalink was '/%category%/%post_id%/', I have changed it to '/%year%/%monthnum%/%day%/%postname%.html' but now trying to access the old links lead to a 404, how can I keep the old system working just for compatibility while keeping the new permalink system in place ??

   oh and BTW my blog is http://wael.nasreddine.com/ an example would be http://wael.nasreddine.com/2008/03/18/beyond-eye-candy.html which was http://wael.nasreddine.com/linux/tip/19

   Thanks :)

   You can add the following code to your .htaccess file, before RewriteCond %{REQUEST_FILENAME} !-f:

   RewriteRule /[a-zA-Z0-9_-]+/([0-9]+) /index.php?p=$1 [R=301,L]

   Not sure it will work though.

   Thanks it worked, but with a little modification to your code:
   

   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule /[a-zA-Z0-9_-]+/([0-9]+)$ /index.php?p=$1 [R=301,L]

   Thanks :)

   Ahh, you should also add /? before $, just in case*.
   Links with trailing (forward)slash wouldn't work.

   Is this a generic fix? I just read this:

   "The best time to set up ‘Pretty Permalinks’ is the moment you install your blog because if you already have a bunch of existing posts, changing the permalink structure will make it so that your old links to those posts will result in page not found errors - to fix this you would need to edit the .htaccess file to set up permanent redirects for each post and page in the form of:
   Redirect 301 http://www.yoursite.com/index.php?p=2 http://www.yoursite.com/the-new-post-title.htm"
   (source)

   Is this solution solving the problem he is addressing?

   I tried the following and got a 404 error when trying to use .htm or .html

   # BEGIN WordPress
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /wp/
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule /[a-zA-Z0-9_-]+/([0-9]+)$ /wp/index.php?p=$1 [R=301,L]
   </IfModule>
   
   # END WordPress

   Still need something that works with version 2.5.1

   Thanks!
   Leslie
