PHP Opcache is not properly configured

[JMC]

I just installed NextCloud on my shared hosting.

On the Admin panel the following warning is shown:

PHP Opcache is not properly configured

I created a php.ini file on the Nextcloud folder, with the following content:

opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

But the error is still showing.

Any ideas?

Shared Hosting
Nextcloud version: 12
Apache: 2.4 (CloudLinux)
PHP version: 7.1
