title: .htaccess file issue
body: <p>When I put a .htaccess file in my root directory it gives me the following error:</p>
  
  <blockquote>
    <p>Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.Please contact the server administrator at admin@localhost to inform them of the time this error occurred, and the actions you performed just before this error.More information about this error may be available in the server error log."</p>
  </blockquote>
  
  <p>Here is my .htaccess code:</p>
  
  <pre><code>RewriteEngine On
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ /login/profile.php?username=$1
  </code></pre>
  
  <p>Basically the function of this code is like when user type his profile name in the url then it display the user profile page via the URI <code>localhost/login/adam</code>.</p>
