[fixed] Php8.0 to php8.2 : white page without php error [php config issue]

Nextcloud version (eg, 20.0.5): 27.1.3
Operating system and version (eg, Ubuntu 20.04): Debian GNU/Linux 12 (bookworm)
Apache or nginx version (eg, Apache 2.4.25): nginx/1.22.1
PHP version (eg, 7.4): 8.2.11 VS 8.0.30

The issue you are facing:

Use php8.2 show a white page before login, no error on php error log. Ok with 8.0.30 on same server (and have other system on 8.2 (phpmyadmin for example).

I didn’t see difference between the 2 setup explain this situation.
I’m sure of my php-error log file (I add a syntax error in checkversion : it shown in my log)
nextcloud-error.log don’t have anything with this white page

Is this the first time you’ve seen this error? Y:

Steps to replicate it:

  1. mv /etc/php/8.0/fpm/pool.d/nuage.example.conf /etc/php/8.2/fpm/pool.d/nuage.example.conf
  2. service php8.0 restart
  3. service php8.2 restart
  4. service nginx restart

/var/log/nginx/nuage.example.net-error.log : empty (old error only)

Output errors in nextcloud.log in /var/www/ or as admin user in top right menu, filtering for errors. Use a pastebin service if necessary.

empty (old error only)

I really don’t have idea on the white page.
Again : i add error on index.php and have it on my php error log, but stay white on clean …

Thanks for the help

Ok,
Have an old disable_functions for 8.2, fixed to get the same than 8.0 : fixed.

Upset because don’t find the error in any log :cry: :triumph:
