After updating PHP to version 7.2.0 icingaweb2 does not work anymore

Icingaweb2 version is 2.4.1 on archlinux.

Will there be a php 7.2 support soon?

Hi,

Thanks for the report. When does this error occur?

Best regards,
Eric

Hi,

Direct after login. Only white page with this error.
After downgrading to php 7.1.12 everything works well again.

Thanks!

Can confirm this is a problem with icingaweb2 version 2.4.2 and PHP 7.2.0.

Can also confirm the downgrade fixes it.

[lippserd]

@draeklae Are you also running Arch Linux?

[lippserd]

I think this is not related to the PHP build on Arch Linux. I reproduced it with Remi's php72 package on CentOS 7.

[draeklae]

@lippserd Arch Linux ARM. AFAIK the PHP packages are identical to the Arch Linux base though.

It should be noted that with PHP 7.2.0 there was a considerable amount of changes regarding session handling, see php/php-src@7f196e3 for example.

FYI: I have exactly the same stated error, im using a regular(x86_64) base arch linux which is up to date. (so thats also php 7.2 and icingaweb2 2.4.2-1)

This will be fixed once #3186 has been merged.
