Vision problems

Server
1

Good morning, I installed owncloud server on site 16.04 and I see this problem in the client. I install php-intl but it can't see it. How do I do this?
I thank you for your kind reply.

No database drivers (sqlite, mysql or postgresql) installed
The PHP intl module is not installed.
Ask your server administrator to install the module.

Maybe you have installed the wrong package or using different PHP versions (5.6 and 7.0?) where the currently active PHP version isn't the one matching whats provided by php-intl?
