Begitu isi notifikasi dari email , lihat jam.. Pheww 10 PM. ya bagaimana lagi, tugas penjaga server. Buka laptop colok modem dan ssh… T_T. Log adalah teman kita ketika ada error, kita bisa tahu dari dia. cek dulu dia sebelum berasumsi.
solusi dari pesan error itu biasanya berada di :

1. Fix permission 755 untuk folder and 644 untuk file

2. Periksa .httaccess

3. php.ini

nah ketika cek log eh ada

Premature end of script headers: index.php

untuk premature…. kompile lagi apache dan phpnya.

/scripts/easyapache

Plus kosongkan semua isi log.

echo > /usr/local/apache/logs/access_log
echo > /usr/local/apache/logs/error_log
echo > /usr/local/apache/logs/suphp_log

restart apache :D dan selesailah, tugas penambal lubang.. *mari main pes*
