Problems with Owncloud 9.01 and PHP 7.0

Hello

I have upgraded PHP 5.6 to PHP 7.0 on my Ubntu 16.0.4 LTS Server.

After I opend Owncloud in the Browser I got these Error.

PHP-V Output:
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies
with Zend OPcache v7.0.10-2+deb.sury.org~xenial+1, Copyright (c) 1999-2016, by Zend Technologies

Error in Webbrowser:

I dont understand these Error because Im running the newest PHP version on my Server.

Thanks for your Help!

You webserver is not updated to load rhe new php runtime (different location)
It is serving php as plain text.

Nginx or apache?

Ich uses Apache on Mythos Server

Moved to miscellaneous as this is not an issue of ownCloud. If you need help with webserver configuration help its mostly also better to contact a community dedicated to your used distro.
