Developer mode version 4

[Stephane]

hi,

I would like use a developer mode for know all variable available in each of my block, database, etc. 

I have a question for you. I upload a last version of developer tools and i created file contants.php and I add a code in my file

<?php
define( 'IN_DEV', TRUE );

But, when I refresh my page, i always have a Whoops page and when i change true for false in constants file, i have this error message.

Fatal error: Uncaught exception 'ErrorException' with message 'Cannot modify header information - headers already sent by (output started at /home2/...../constants.php:1)' in /home2/...../init.php:516 Stack trace: #0 [internal function]: IPS\IPS::errorHandler(2, 'Cannot modify h...', '/home2/...../pub...', 516, Array) #1 /home2/...../init.php(516): header('HTTP/1.1 500 In...') #2 /home2/...../init.php(495): IPS\IPS::genericExceptionPage() #3 [internal function]: IPS\IPS::exceptionHandler(Object(ErrorException)) #4 {main} thrown in /home2/...../init.php on line 516

All of applications IPS is installed.

Thank's in advance for your help,

Stef

All it's ok... I recreate my constants.php with textedit (not with dreamweaver)...

Thank's for the Invision Support...
