'Headers already sent' error messages

tday · Unread post by **tday** » Fri Feb 28, 2014 11:47 pm

Really liked the demo (great succinct tutorials!) and want to give nuBuilder a try.

The install on a remote host (Hostpapa) went fine until it came to loading nuinstall.php. This gave 'headers already sent' messages. Also tried on local xampp server (PHP 5.3.0) with the same outcome

After googling the problem , I edited nuinstall.php by moving 'Session Start' to the top of page - this worked and I could then create the database. But then index.php gave similar 'headers already sent' error messages.

Rather than attempting more edits, could these error messages be related to a PHP version issue or maybe parameter setting somewhere?

Hi,

I've got the same problem.
I renamed session_start(); to @session_start();
in nucommon.php but that only suppresses the error messages.

It's no solution.

Don't know if this problem is also the cause of any other problems?

Hi!
I have the same issue here with a webhost (Linux, Apache, PHP Version 5.2.17).
I tried to re-install and google the issue but it seems that the session should be started before pushing HTML.

But then, why doesn't everyone have the issue?

Kind regards,

Joe

To my opinion: it's a blocking issue??

Howto debug this?

Howto debug this?

Hans,

Edit index.php and insert

Code: Select all

<?php
require_once('config.php');
require_once('nucommon.php');
?>

as the first two lines. Remove line 18 and 19.

That seems to do the trick for me. Again, I don't understand why not everyone has this issue.

Kind regards,

Joe

Hi Joe,

That solved the first problem.

Thanks.

(2nd step I suggest is to create a form with the Form Wizard?)

Hi,

I have just installed nuBuilder and I am getting this error (on both the nuinstall.php index.php pages), I have tried the fix above and I get the following error

Code: Select all

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /var/sites/f/mydomain.com/public_html/index.php:11) in /var/sites/f/mydomain.com/public_html/nucommon.php on line 5

my Index.php is as follows

Code: Select all

<?php
require_once('config.php');
require_once('nucommon.php');
?>

Yeah it looks like that last post is the solution.

I've came here at first looking for that error message and looking at the DATES involved with the issue (one year ago) I still posted a request, because apparently this issue is still there after one year.

This is a bit of what I'm clueless about, why the files I download today are not fixed as stated above after all that time?

Might have been one left out by admin

Thanks to all anyway.

Installed nuBuilder approx. a year ago and it didn't work properly.
My hostingprovider upgraded to the latest of php and mysql.
Problem is, after a year?, still not solved.

Could it be that my hosting is on a 32Bit machine?

I applied the workaround and the error is gone.

I signed up with http://www.hostpapa.com/ and uploaded the latest download from https://github.com/nuSoftware/nuBuilder ... master.zip
and I found the same error.

I have now updated index.php to fix this.

you can patch the file from this link: https://github.com/nuSoftware/nuBuilder ... /index.php

Please let me know if there are any other problems related to this.
