PHP 8.4.13, session_set_save_handler()

[olafgleba]

Hi,

since i updated my local PHP to 8.4.13 (from 8.2), all PW installations are quirky. Regardless what 3.0.x.x.x PW versions.

On load (Backend/Frontend):

Deprecated: session_set_save_handler(): Providing individual callbacks instead of an object implementing SessionHandlerInterface is deprecated in [...]/wire/core/WireSessionHandler.php on line 51

Followed then by:

PHP Warning:  session_set_save_handler(): Session save handler cannot be changed after headers have already been sent in [...]/app/wire/core/WireSessionHandler.php on line 51

Although it is a deprecation/warning, it has effect on the behavior within the Backend (page tree doesn't load etc.) when debug is on. 

I also tried to upgrade a local PW installation (v. 3.0.242) to the latest master/dev, the folders and files are created (wire, index.php etc.). But loading the backend or frontend both gives completely blank page immediately. Fortunately the rollback works.

I did a search, but found not much on this topic, i am afraid.

Emptied all caches, compiled files multiple times.

Does anyone have a clue what to do or where to look at?

Thx in advance
Olaf

Thanks, @matjazp. I need to get myself looking at the github issues more regularly.
