Internal Server Error after upgrade

So I was upgrading OwnCloud this weekend and have since been getting an internal server error when trying to access. At first it was the PHP version error. So I upgraded to php7.0. I’m now at least able to get to what looks like the splash screen, but it’s just the error. From what I can tell it’s related to mysql, but I can’t figure out what. My database is hosted on a remote database (not the same machine). It was 100% working prior to attempting this upgrade…please give me some pointers. I haven’t been able to find anything online.

Steps to reproduce

  1. Navigate to server IP address

Expected behaviour
Should see the normal login splash screen.

Actual behaviour
I see an internal server error screen.

Server configuration
Operating system: Ubuntu 16.04

PHP version: 7.2.5

ownCloud version: Upgraded to 10.0.8

Updated from an older ownCloud or fresh install: Updated from an older version.

Where did you install ownCloud from: Updater on Admin page

The content of config/config.php:

<?php $CONFIG = array ( 'instanceid' => '******', 'passwordsalt' => '******', 'secret' => '******', 'trusted_domains' => array ( 0 => '192.168.1.74', 1 => '******', ), 'datadirectory' => '/var/www/html/andycloud/data', 'overwrite.cli.url' => 'http://192.168.1.74/andycloud', 'dbtype' => 'mysql', 'version' => '9.1.8.2', 'dbname' => 'andycloud', 'dbhost' => '192.168.1.73', 'dbtableprefix' => 'oc_', 'dbuser' => '******', 'dbpassword' => '******', 'logtimezone' => 'UTC', 'installed' => true, 'mail_smtpmode' => 'smtp', 'maintenance' => false, 'updater.secret' => '*****', 'loglevel' => 2, 'htaccess.RewriteBase' => '/andycloud', );

Hi,

How did you upgrade?

It looks to me that there are some PHP extensions missing. Maybe you can compare the installed ones with the ones listed here:

https://doc.owncloud.org/server/latest/admin_manual/installation/source_installation.html#install-the-required-packages

Dmitry, I upgraded via the updater on the admin page.

tom42, I’ll check out that link. Thank you.
