PHP Fatal Error: Uncaught TypeError upgrading from 4.1.3 to 5.1.1

When I start the update by navigating to the /adserver_new directory I get a blank page with error 500 and this is produced in the error_log file:

I had the same. Error was thrown by reading the configuration file. It was not able to read or parse some values, or someting like this. I'd simply put some values (e.g. database password) in quotation marks and it worked.

Thanks, using quotations around the database credentials solved the problem for me too.

The copy of the config file did not use quotes, was this a documented change or caused by some server configuration?
