PHP-Error -> HTTP 500 when sending Mail

Hey Guys,

I get an error when sending Mails from WebApp (HTTP 500). Apache Error.log sais

[Sun Jan 21 09:46:59.378959 2018] [:error] [pid 1111] [client 95.222.30.124:5156] PHP Fatal error: Call to undefined function dump() in /usr/share/kopano-webapp/server/includes/core/class.operations.php on line 4003, referer: https://*************/webapp/

It used to work perfectly. Seems to be a Problem related to latest System/Kopano-Updateds.

May you plz check this.

Thank you verry much!

Hi @faithless1108 ,

we looked into this and at first could not reproduce it. Looking a bit further into this it seems you are missing the following lines in your config.php. Once you have added them you should be able to send mails again.

Hi @fbartels,

i already got these lines in my config.php

if (file_exists('debug.php')){
	include_once('debug.php');
}else{
	// define empty dump function in case we still use it somewhere
	function dump(){}
}

What now?

Since you are running our supported packages I assume you also have a valid subscription. Therefore I would recommend to get in contact with our support and have someone look at your system.
