Thank you for taking the time. Any backup that I restored using duplicator is in latin1. If you check the SQL database, you can see that too.
Please note that I double checked my wp-config.php file. Anything is correct until I restore the backup. That s why I decided to go with another plugin now. It took my app. 2 days to find out how my db_charset changed.

Thank you for answering so quickly, dizzyatinnocraft!

1. nginx error log says after triggering…:

2) php (error.log does not contain infos with corresponding time stamps) php-fpm.log says:

3) there is no such file …//wp-content/debug.log

I suspect that the error happens too early to create a debug entry. How shall I proceed? Thank you.
