Today I struggled installing Nextcloud / Owncloud on my Ubuntu 16.04 Server through Plesk Onyx Version 17.5.3.
I was getting the following error message:
English:
PHP module zip not installed. Please contact your server administrator to install the module. PHP modules have been installed but are listed as missing? Please contact your server administrator and ask to restart the web server.
German:
PHP-Modul zip nicht installiert. Bitte für die Installation des Moduls Deinen Server-Administrator kontaktieren. PHP-Module wurden installiert, werden aber als noch fehlend gelistet? Bitte kontaktiere Deinen Server-Administrator und bitte um den Neustart des Webservers.
Since I did, after some experimenting, manage to get around this problem I wanted to share the solution with the community.
Read the answer below…
Your domain is configured with the wrong PHP version. In my case it was 7.0.30. In order to change this, go to:
Domins -> mydomain.tld -> PHP Settings -> PHP-Version
and set this to 7.2.9
If 7.0.30 is the only version available, go to:
Tools & Settings -> Updates and Upgrades -> Add Components -> Web Hosting -> PHP Interpreter Versions
to install other PHP versions.
