error on delete or update order

[killerwhale65]

Hello,

 

When i try to delete, or update an order, i get this error:

 

Warning: Cannot modify header information - headers already sent by (output started at
/home/artofmodel/domains/artofmodelling.be/public_html/beheer/includes/languages/dutch/orders.php:5)
in
/home/artofmodel/domains/artofmodelling.be/public_html/beheer/includes/functions/general.php
on line 22

 

The order does get deleted or updated, but the error is annoying and the order page is not shown.

 

what could be wrong?

 

thanks!

 

Matt

This is usualy due to whitespace at start/end of file, created when editing file or by some 'bad' editors.
