copied!<p>It's possible that your routes aren't resolving correctly, but I'm not sure. I'd recommend the following steps.</p> <p>First, I would just do away with using <code>PATH_INFO</code> for your CodeIgniter routing, as it's not necessary. Change your <code>.htaccess</code> file to this:</p> <pre><code>RewriteEngine On RewriteCond $0 !^(index\.php|images|captcha|css|js|robots\.txt) RewriteRule ^.*$ index.php [L] </code></pre> <p>Then, in your configuration, make sure that <code>$config['uri_protocol']</code> is set to <code>AUTO</code> (the default, I believe) or <code>REQUEST_URI</code>.</p> <p>Following that, the most likely cause is that your routes expect there to be a trailing slash on the URL. I don't know enough about CodeIgniter to know where that particular setting is configured, but you can cause your URLs to have a trailing slash with the following configuration directive:</p> <pre><code>$config['url_suffix'] = "/"; </code></pre> <p><strong>Edit</strong>: Make sure that <code>mod_rewrite</code> is working, as well. Try this at the top of your <code>.htaccess</code> file, after the <code>RewriteEngine</code> directive:</p> <pre><code>RewriteRule .* http://stackoverflow.com/ [L,R] </code></pre> <p>If you get redirected to Stack Overflow, at least we'll know that's working. If not, you aren't getting a 500 error, so the problem would lie with the <code>.htaccess</code> file, and in that case you should confirm that the corresponding <code><Directory></code> entry in your server configuration for where your site is located on disk has <code>AllowOverride All</code> set.</p> <p><strong>Edit</strong>: I should have known better about the forward slash, sorry about that. The problem occurs because of how <code>mod_rewrite</code> works in your per-directory (<code>.htaccess</code>) context.</p> <p>Once your URL is rewritten, it is examined to determine what <code>mod_rewrite</code> should do with it. When your URL points to a local resource and contains a leading slash, <code>mod_rewrite</code> leaves it as-is. When it does not, it adds the per-directory prefix.</p> <p>When it's left as-is, an internal redirect to <code>/index.php</code>, in this case, is assumed to be a fully-qualified URL from the host (localhost). So, the resource requested ends up being <code>http://localhost/index.php</code>. When the per-directory prefix is added, a later step in the rewrite engine attempts to remove the <code>DocumentRoot</code> from the path, if it's present. This leaves us with <code>/kids/index.php</code>, which is then passed to the internal redirect, and is resolved as expected.</p>
