In the officiall documentation for Owncloud 9 it says:
'htaccess.RewriteBase' => '/',
To have clean URLs without /index.php this parameter needs to be configured.
After setting this value run occ maintenance:update:htaccess [...]
However, running "occ maintenance:update:htaccess" will result in an error:
There are no commands defined in the "maintenance:update" namespace.
Can I update my .htaccess file manually?
