The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

$CONFIG = array (
  'instanceid' => 'ocrdatkotesx',
  'passwordsalt' => '0biAcIfoBcWtShSAS7lDAaTW8SEE3R',
  'secret' => 'zewqfyfdNgtzy3wd1vF8cz8rBRth0p7+ZFA58zdZLp0PDpCs',

  'overwrite.cli.url' => '',
  'installed' => true,

tail -f /var/log/apache2/error.log

Good morning mate, hope you are doing well…

First of all, you may need to delete your instanceid from the cache, do it running this:
sudo -u apache php /var/www/html/nextcloud/occ config:system:delete instanceid

Then, try rebooting your server and test it. If this do not solve your problem, run this:
1) sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --on
2) chown -R www-data:www-data /var/www/nextcloud/
3) chmod -R 770 /var/www/nextcloud/
4) sudo -u www-data php /var/www/nextcloud/occ maintenance:repair
5) sudo -u www-data php /var/www/nextcloud/occ db:add-missing-columns
6) sudo -u www-data php /var/www/nextcloud/occ db:add-missing-indices
7) sudo -u www-data php /var/www/nextcloud/occ maintenance:update:htaccess
8) sudo -u www-data php /var/www/nextcloud/occ maintenance:mode --off
9) sudo systemctl restart apache2

Also, check your php version running “php -v”, that can help a lot.

Make sure you have php-fpm installed and running.

Hope this helps, have a nice weekend.

All the best!

Make sure your file only starts with:
