Blank page after server validation

Hi

After applying server validation to a page with a form the page returned after submiting is blank.

I use DW5.5 and CSS Form builder 2.0.1

Any hints are highly welcome

a blank page means a php error is occurring, but error reporting is turned off.


add the following code at line 1 to turn error reporting on:

php:
<?php

error_reporting
(E_ALL);
ini_set('display_errors','on');
?>

Thanks Jason

I just did that and got the following error message:

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\W3DC\test1.php:5) in C:\xampp\htdocs\W3DC\webassist\form_validations\wavt_scripts_php.php on line 83

Strangely it worked all before I reinstalled CSS Form Builder 201, FormTK100 and Security Assist 205.

The error just ocures when I use the Validation Show if behaviour

Maybe to add,

I created a form in CSS Form Builder called it in the same page via
<?php
require_once($DOCUMENT_ROOT . "registration.php");
?>
and it works - the error I get only if I manualy place a form, add the Server Validation and then add the Show if behaviour

in the file you attached, there is a blank line at line 1 and at line 9 that will cause the error you are reporting.
