Server configuration

Operating system: Debian

Web server: Apache

Database: Mysql

PHP version: 7.3

Nextcloud version: master

Login as admin user into your Nextcloud and access 
http://example.com/index.php/settings/integrity/failed 
paste the results here.

Can't get the result, page returns "Integrity checker has been disabled. Integrity cannot be verified." even if I put `'integrity.check.disabled' => false` or `'integrity_check_disabled' => false,` in config.php. Another bug?
