Ok, i received the error log from my provider. After doing some research, it is due to php server setting error_reporting was set to 22527. I found out 22527 value represent E_ALL & E_NOTICE.
So I have inform my provider to change the error_reporting to 22519 which represent E_ALL & ~ E_NOTICE.
I also tried to use other method to override the value through .htaccess, php.ini, php5.ini and user.ini custom file saved in my web directory. Unfortunately it doesn't work as intended. Maybe I did it wrong, what I did was to add error_reporting = 22519 in each of the custom file above. I have also tried using the value E_ALL & ~E_NOTICE but no luck either.
Maybe my provider disable adding custom php setting.
