Nextcloud version (eg, 20.0.5): 20.0.8
Operating system and version (eg, Ubuntu 20.04): shared host (CPanel), Kernel: 3.10.0-1160.6.1.el7.x86_64 x86_64
Apache or nginx version (eg, Apache 2.4.25): 2.4.46
PHP version (eg, 7.4): 7.4.16
The issue you are facing:
cron.php uncaught error (see “Logs” below)
Steps
I’ve added Nextcloud’s cron.php as a cron job (every minute !):
* * * * * php -f /home/SECRET_PATH/public_html/nextcloud/cron.php
After that in “Admin / Settings / Administration / Basic Settings / Background jobs” I’ve changed the options to “Cron”.
After that I get this message:
Last job execution ran 55 minutes ago. Something seems wrong.
On the host if a cron job produce an output, the system (CPanel) sends me an email with the output.
To make sure that the cron.php is called I wrote an echo "hello"; in the cron.php right below <?php and I started getting email with “hello” every minute.
So the cron.php is called every minute, but the Last job execution... error message still there on the web UI.
I’ve moved the echo "hello"; to different places in cron.php and it seems to me if I put the echo after require_once __DIR__ . '/lib/base.php'; the execution never reach the echo "hello";

try {

echo "hello";
Etc
This is a shared host server (CPanel) so everything is running with a same user
