Since there are no other plain HTTP virtual hosts, the one defined for
chmod777.sh became the "default." Since it explicitly redirects all
requests to https://chmod777.sh, it caused all non-HTTPS requests to be
redirected there, regardless of the requested name. This was
particularly confusing for Tabitha, as she frequently forgets to put
https://…, and would find herself at my stupid blog instead of
Nextcloud.
