any problem of my code that causing my page sometime to load as blank page?

mrMarcus · October 8, 2009

do you have error_reporting on?

Adam · October 8, 2009

Okay, break down the problem...

If you remove the PHP at the top, does the error still occur?

If you remove the meta content tag, does the error still occur?

When the page loads blank, what is in the source?

As mrMarcus just asked, do you have error_reporting disabled?

orange08 · October 12, 2009

do you have error_reporting on?

yup, the error_reporting is on, but when the page is loaded as blank, no any error being output...

Adam · October 12, 2009

... and what about the other questions?

Okay, break down the problem...

As mrMarcus just asked, do you have error_reporting disabled?

yup, i have tried before post the code here...

even though i remove all php code at the top, only left there the following code

<?php
  session_start();
?>

the page still will be loaded as blank...

then, if i remove all php code including the <?php session_start(); ?>, then the page will never load as blank again...

i'm really can't figure out what's the problem here. :confused:
