I'm not the good DrByte, but it appears that somehow there is a character before the opening <?php in the file: includes/classes/ajax/zcDPU_Ajax.php that is on your server. I have just downloaded the plugin and at least in the file viewer I am looking at such a character does not exist. How was the file uploaded/installed?

Further assistance regarding the warning message of Headers already sent can be found at this FAQ: https://www.zen-cart.com/content.php...s-already-sent

Please report back what you find as it would be nice to know if the original fileset was found to cause this issue so that it could be prevented for others. I don't have those error messages in the installation that I have so would have to figure out what caused the introduction of an additional character (visible or non-printed) at least to ensure it wouldn't be present for others.

I just checked and there is no character at the opening

<?php

class zcDPU_Ajax extends base
{
function dpu_update()

What else could be the reason for this?

The file was somehow uploaded with the incorrect file encoding (UTF-8/BOM) so there is an "invisible" character at the beginning of that file. I have uploaded to github just the change to the encoding (ANSI) to: https://github.com/mc12345678/Dynami...79eea406dd84cf.

[mani]

It appears using your file has fixed the problem!

Thanks a lot :)
Much appreciated!

Now got one more warning

[18-Jul-2017 06:57:14 UTC] PHP Warning: Invalid argument supplied for foreach() in /home/yabba1/public_html/includes/classes/dynamic_price_updater.php on line 150

How do I get this fixed?

[mani]

Is this version of this module GitHub
https://github.com/Zen4All-nl/Zen-Ca...eases/tag/v3.1

Same as this one
https://www.zen-cart.com/downloads.php?do=file&id=1301 ?

In Github version there is no ajax folder in includes/classes

If I install GitHub version will it work with 1.5.5e?
