Hi, have you read the docs?

here is how you install the required modules:

https://doc.owncloud.com/server/10.0/admin_manual/installation/source_installation.html#on-ubuntu-16-04-lts-server

Thanks for the help, I've already solved it

What was the resolution?

if the modules are installed, you can try to restart httpd(Apache) service.

Hey,

i think the solution is to read the documentation and install/enable the required modules/extensions for ownCloud.
