Hari ini dapat info dari teman saya kalau website kantor saya tidak bisa di akses dikarenakan .htaccess belum di set. Akhirnya langsung meluncur ke TKP untuk memeriksa, apa benar website error? Teryata waktu saya cek halaman front page sudah oke tidak ada masalah, tapi ketika masuk ke menu akan keluar error seperti ini :

Not Found

The requested URL /Comfort__Convenience.html was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Ssetelah saya analisa sebentar, ternyata info  yang saya terima benar yakni hal tersebut karena kesalahan pada setting .htaccess. File .htaccess punya saya kosong alias tidak ada isinya sehingga mengakibatkan modul OpenSEF yang saya pasang pada engine joomla tidak dapat berjalan dengan baik. Jadi bagaimana solusinya?

Anda tinggal buka file .htaccess pada root directory, kemudian isi dengan kode berikut ini :

#
# @version $Id: htaccess.txt 5975 2006-12-11 01:26:33Z robs $
# @package Joomla

# Only use one of the two SEF sections that follow.  Lines that can be uncommented
