@f-hamel can you please test the patch provided by @mbabker ?

If you need help with that feel free to ask questions. As I personally don't have a server with APCu enabled.

You can find a documentations how you can test here in detail: https://docs.joomla.org/Testing_Joomla!_patches

The easiest way would be to download & install the latest nigthly build for Joomla 3.9:
https://developer.joomla.org/nightlies/Joomla_3.9.0-dev-Development-Full_Package.zip
Install the com_patchtester component:
https://github.com/joomla-extensions/patchtester/releases/tag/2.0.1
Refresh the data.
use the search bar to get to the PR ID: 19990 & hit apply patch.
Than you can try to use apcu as session storage as requested in your issue.
Please report any questions / issues or suggestions to this page so this can be discussed & adressed.

Please note that this only can get merged into the core & released if we have tests on this code proposal. Thanks 👍

@zero-24 and @mbabker I'm sorry. I was little bit busy the last days.
So thanks for remembering and this good testing instruction.
I could apply the patch and test.

There was no unexpected behavior.
APCu Session storage is available and works fine.

@mbabker can you update that branch to 3.9-dev so we keep drone happy.

I would like to move this RTC than given that the code bases on the framework and @f-hamel 's test on a live environment.

Ah they just enabled the push button :)

RTC. Thanks 👍

Is this valid for 4.0 too? Or do we have there APCU from the framework package?
