Custom Structure permalinks error 404

Question

i have changed the wordpress custom structure permalink to /%post_id%/%postname%/ and get this error :

404 Not Found The requested URL /mysite/blog/1/hello-world/ was not found on this server.

• wordpress version 3.1.7
• site address: localhost/mysite/blog

i'v changed this function in misc.php and saw the error again!

function got_mod_rewrite() {
    //$got_rewrite = apache_mod_loaded('mod_rewrite', true); //old line with false negative;
    $got_rewrite = true;//force the response to true as we know mod_rewite is installed;
    return apply_filters('got_rewrite', $got_rewrite);
}

Mehdi, it's common problem, as Apache server is not set by this way by default. Your problem can be solved with some very simple steps (simply quoting Samuel B):

If you want to use permalinks, you will need to make a change inside another file: apache > Conf and find the file httpd.conf. Open that in a text editor. Use the search facility in the editor to find "rewrite". The line you need looks like this:

#LoadModule rewrite_module modules/mod_rewrite.so

You need to take away the hash sign so it looks like this

LoadModule rewrite_module modules/mod_rewrite.so

Now just save the file.

I wanted to use Custom Structure permalinks like this: www.example.com/blog/post/%post_id%/%postname%/

But just putting this /blog/post/%post_id%/%postname%/ in the custom structure resulted in 404 error.

I was able to resolve this issue by putting this in the custom structure field after reading some articles & trial n error: /index.php/blog/post/%post_id%/%postname%/ .

I use nginx.
