title: Error after activating SEO Settings in Joomla 2.5
body: <p>I am using Shape5 Corporate Response template for Joomla 2.5</p>
  
  <p>In order for me to activate the SEO freidnly website I had to:
  1- Change htaccess.txt to .htaccess
  2- In global configuration change Search Engine Friendly URLs from No to Yes
  3- Change Use URL rewriting From No to Yes</p>
  
  <p>after that the template runs but the menu that I created does not work and when I click on it, it says:</p>
  
  <blockquote>
    <p>Not Found</p>
    
    <p>The requested URL /contact was not found on this server.</p>
    
    <p>Additionally, a 404 Not Found error was encountered while trying to
    use an ErrorDocument to handle the request.</p>
  </blockquote>
  
  <p>I already did this test :
  <a href="http://docs.joomla.org/How_to_check_if_mod_rewrite_is_enabled_on_your_server" rel="nofollow">http://docs.joomla.org/How_to_check_if_mod_rewrite_is_enabled_on_your_server</a></p>
  
  <p>and my mod rewrite is enabled.</p>
  
  <p>also I edited "# RewriteBase /" to  "RewriteBase /" in htaccess but no luck.</p>
  
  <p>here is my htaccess:</p>
