Acknowledgment E-Mail Link no longer workings

[sjka]

Hello,

i'm a fairly new user of Zabbix, < 2m, thus my knowhow about Zabbix is at a beginner level.

That's how our Zabbix is setup:

Zabbix 6.0
Ubuntu 20.4.3
Postgres 13.x
Nginx


I updated from 5.4 to the latest 6.0 today and after a few tests i saw that the acknowledgment link no longer works.

If i want to update one problem via webgui, this is how the link looks like:

Chrome: zabbix.php?action=popup&popup_action=acknowledge.e dit&eventids%5B13542%5D=13542
Firefox: zabbix.php?action=popup&popup_action=acknowledge.e dit&eventids%5B13542%5D=13542

Chrome: zabbix.php?action=popup&popup_action=acknowledge.e dit&eventids%5B13540%5D=13540&eventids%5B13542%5D= 13542
Firefox: zabbix.php?action=popup&popup_action=acknowledge.e dit&eventids%5B13540%5D=13540&eventids%5B13542%5D= 13542

%5B = [
%5D = ]

If i copy and paste these links in the same/ a new tab, following error occurs:


I want to append an Acknowledgment link to the Email under Actions -> Operations -> Custom Message.

Thanks in advance.


EDIT: The space between acknowledge.e dit doesn't exist, can't get rid of it here in the forums.

What do you get in your nginx logs during this time? And what version PHP?
