Could not install Owncloud version 10.0.8

Hi,
there was a “read the faq first” information … but i could not find the faq.

I used owncloud for many years but not for the last year. I decided to make a fresh install (no need of a backup) and go for Version 10.0.8.

So i create a database, a owncloud folder and upload the data files including the config file.

but if I want to start the installation i get just this error message

Fatal error: Uncaught Error: Call to a member function getLogger() on null in /homepages/16/d508845845/htdocs/own/index.php:88 Stack trace: #0 {main} thrown in /homepages/16/d508845845/htdocs/own/index.php on line 88

Maybe one of you has a solution for my problem

best regards,
nebu

Here is a good point to start figuring out what went wrong
