title: OpenCart- File not found (404 error) on category pages
body: <p>I have Opencart Version 1.5.6.4_rc, clean install.  </p>
  
  <p>I have created several product categories(with SEO friendly URLs), however, on clicking on category link it always shows the error - File not found(404 error).</p>
  
  <p>I have checked there are no spaces between URL characters. The error is specific to category pages, information pages are fine.</p>
  
  <p>My Htaccess looks like this.</p>
  
  <pre><code># 1.To use URL Alias you need to be running apache with mod_rewrite enabled. 
  # 2. In your opencart directory rename htaccess.txt to .htaccess.# For any support     issues please visit: http://www.opencart.com

  # If you get an "Internal Server Error 500" after enabling any of the following settings, restore the # as this means your host doesn't allow that.

  #php_value post_max_size 999M
