Err: Rewrite url not working in Ubuntu

    The problem may occur due to that module is not enabled yet.


    To enable the module in Ubuntu
          $ a2moden rewrite
          $ /etc/init.d/apache2 restart

    And do the following changes in 'default' file under /etc/apache/sites-available
          Change the line 'Allowoverride None' to 'Allowoverride All' inside the respective folder directory.
