ispconfig gets a white screen.

Debian 11 with kernel 5.10.0-42-amd64
PHP 7.4.33
ISPConfig 3.3.1p1
Did an apt-get upgrade. Also upgraded the kernel to 5.10.0-42-amd64.
After upgrade and reboot, cannot get acess to ispconfig.
Getting a white screen.
Got the following error.

Code:

Uncaught InvalidArgumentException: Please make sure the folder '/usr/local/ispconfig/interface/lib/classes/IDS/../../../temp' is writable in /usr/local/ispconfig/interface/lib/classes/IDS/Monitor.php:159

Tried changing the permission of temp to 777 and the files inside to 666 but did not work.
The files are already owned by ispconfig user.
Then did the solution from the following link.
https://forum.howtoforge.com/threads/ispconfig-error-500.93106/
Commented out the following in /usr/local/ispconfig/security/security_settings.ini

Code:

[ids]
#ids_anon_enabled=yes
ids_anon_log_level=1
ids_anon_warn_level=15
ids_anon_block_level=20
#ids_user_enabled=yes

And I can get access. Phew for now.
I want to put it back to where it was.
What do I need to do in Debian to bring back to where it was?
