After NC Install: "No input file specified."


i made a fresh install of NC13, i used the admin Installation Manual from the Nexctlcloud site!
But after every Installation it ends when i want to open the url with "No input file specified. "

My System:
Ubuntu 16.04.3 LTS‬
Plesk Onyx 17.5.3
NC 13
Apache2 Webserver and PHP 7.0.25

Here’s what i did for the test Install:

-Created a Subdomain for NC “

-Installed every required and recommendes Modules for NC13

-Downloaded the NC Zip File, Unziped it and copied everything with “cp -R /nextcloud/*” to “/var/www/vhosts/”

-Created a Apache Webserver Config:
Alias /nextcloud “/var/www/vhosts/”

<Directory /var/www/vhosts/>
Options +FollowSymlinks
AllowOverride All

Dav off

SetEnv HOME /var/www/vhosts/
SetEnv HTTP_HOME /var/www/vhosts/

-Created a symlink for that config

-Changed Permissions for the directory to “chown -R www-data:www-data /var/www/vhosts/”

When i now open the URL it tells me "No input file specified. "!
It’s not the first time i use Nextcloud, and before i already had run several OC Installs without trouble… so i guess it’s a very simple problem…
Server Installation is nearly fresh, so there are no changes on the apache webserver! Everything Standard!

I hope you can help me on that one!


Any additional Info needed to help me? No ideas whats going wrong since my last try’s to install nc?
