Dear Community!
I am moving a working Drupal 8.4 installation from an ubuntu on raspberry to a centOS 7.3 (root server). On the target system there are other running websites, including a working Drupal 8.4
My problem: after migration, including install of composer, setup of MariaDB 10.2, copying of files (rights checked), I can get the static files, like robots.txt, but I get errors with the drupal pages: »The website encountered an unexpected error. Please try again later.«
I cannot use <my.server.tld>/update.php – same error; in /var/log/httpd/error_log I find a lenghty error text – the same text I get when I call <my.server.tld>/core/install.php, this time well formatted on screen.
Could not find any hint in forum helping me further – can you help me?
Thanks in advance,
Michael
