[details=“White Screen of Death”]
After my Ubuntu Server crashed (Raspberry Pi 4B+, 8gb) after an update, i restored it. Thankfully, all the Nextcloud resources run on an external drive.
occ is working (as long as I use -d memory_limit=-1).
Looking into Apache2 error log indicated that PDO wasn’t installing yet php indicates it is installed.
Nextcloud Server 24.0.4
MySQL 8
php8.0-fpm
Apache2
Ubuntu Server 20.4
I followed all ideas making sure that php8.0-fpm was enabled with mpm_event. Enabled mysql_pdo in php.ini (for php8.0 fpm). Disabled php8.0.
After updating these options, the log in screen doesn’t appear?
This is the installed options from test.php

Since the restoration, Nextcloud hasn’t detected memcache.
occ works but -d memory-limit = -1 must be entered even though the memory setting for php.ini are set for 512M.
Tried installing Nextcloud into a new folder, the screen loading with an error message indicating mysql_pdo wasn’t installing.
Since the server restoration, php 8.0 hasn’t been functioning the same way before the server crash.
