I have tried to auto-update to the latest version.
I had to update php to 7.4.0, which I accomplished
php -v results in:
PHP 7.4.30 (cli) (built: Jun 27 2022 08:14:52) ( NTS )
Copyright (c) The PHP Group
Zend Engine v3.4.0, Copyright (c) Zend Technologies
with Zend OPcache v7.4.30, Copyright (c), by Zend Technologies
Now I am getting the "We are sorry, but a MySQL - error occurred. The administrator may find more information in the syslog" error.
Any advice is appreciated.
(e.g. where to read the syslog without web interface - maybe I can proceed from there, but if anyone has more insights, any help is welcome)
