Headers already sent

Suite and Optimus Suite 5

Hi to all,

I coded an applikation on my local machine (Windows XP, XAMPP). All works fine. After copy to our Webserver (Windows XP, XAMPP), I allways get following message:

Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\besi\mod\abl\xml\auftrag\auftragDetails.php:1) at C:\xampp\htdocs\besi\dhtmlx\connector\base_connector.php line 37

I know about this message, but I don´t know why, because on my local systems all works correctly. Is it possible, that I have got a PHP version problem? Local works 5.3.5, on server works 5.3.1

Can anybody help me?
Kindly regards
Daniel

You can have output buffering enabled on your dev PC and disabled on the server.

Also, check your php files involved in connector’s call - in one of them you have some output ( echo, print command, or just whitespaces outside of php block )

Hi Stanislav,

thanks a lot, well done :bulb:

output buffering was disabled in my php.ini file. After set to 4096 all works fine now.

Thanks
