PHP Fatal error: Incompatible Declaration

[glorpen]

int / void type was introduced in Kimai v2.0.0, could it be that you installed glorpen-duration-plugin in version 2.0 on Kimai v1.x?
If it is the case, try with https://github.com/glorpen/kimai-duration-plugin/tree/v1.0.2 instead - same functionality but for Kimai 1.x.

I am pretty sure that I am using the latest kimai/kimai2:apache docker image. Could it be that the types have been removed again in the upstream?

Well, using kimai/kimai2:apache would explain it, seems that not all of their images with "latest" tags are v2:

docker run --rm -it --entrypoint '' kimai/kimai2:apache cat /opt/kimai/version.txt
1.30.11
docker run --rm -it --entrypoint '' kimai/kimai2:apache-2.0.10-prod cat /opt/kimai/version.txt
2.0.10

Okay, thank you for this clarification. I wasn't aware that there is something weird going on with the versions (see tobybatch/kimai2#503 (comment))
