[Lam-public] Web I/F unresponsive when creating/modifying user password

[Bzzzz <laz...@gm...>]

OS : Debian bookworm (aarch64)
FPM: 8.2
LAM: 8.4.1 (pkg from the site)
==============================
Hi,

All is in the title, if I try to create a user with he's P/W, as soon
as I click OK in the P/W popup the GUI is completely unresponsive, the
only way to recover is to reload the page, but it cancels the P/W input
:(

It is the same if I :
* create the user without a password,
* get out (either back to the users' list or even disconnecting),
* come back and try to modify this user's P/W.

At first I though it was a bug in the Debian pkg, so I installed the
site one, but it is still the same mess.

The symptom is no button nor link work anymore and hovering them do
not change the mouse cursor shape anymore too.

The machine is a Raspberry Pi-4 8 GB RAM pushed to 1,900 MHz that is
_very_ table.

So a bit of help would be very welcome.
