oh boy, This DID mess something up.
I do not have nextcloud installed
php expects a nextcloud pool (user has not been defined)
nextcloud pool expects a directory at /var/www/nextcloud
php pool nextcloud can not get uid for user nextcloud.
(my mediawiki and roundcube are down because of this, too.)
Not sure how to get past this.
Please advise.
