What version of PHP are you using? The first few releases in the 6.0.x series required PHP 7.2.5, 7.3.x, or 7.4.x, but not PHP 8.0. Recent Zabbix 6.0.x releases (6.0.6 and later, I think, check the documentation) now support PHP 8.0 and possibly PHP 8.1.

It seems like zabbix installed php-fpm 8.0 when i installed the packages how do i downgrade it to 7.2?

Requirements page (https://www.zabbix.com/documentation...n/requirements) says:

PHP	7.2.5 or later, (since Zabbix 6.0.6) 8.0, 8.1

yeah but later in 6.0 is 7.4 or is it up to php 8.0? because if 6.0 supports php 8.0 the problem still persists

[Markku]

It means: with Zabbix 6.0.0 - 6.0.5 you can use 7.2.5 or newer but 7.x series only, and with Zabbix 6.0.6 and later you can use 7.2.5 or newer up to and including 8.1.x.
