@LoudLemur looks like the DNS record was pointing to a Cloudron which didn't have any app installed on that (sub)domain. If a Cloudron server as such just gets deleted, then the DNS records are not automatically cleaned up, since there is nothing running anymore to do that.
@privsec I enabled all modules you were showing in the screenshots but I cannot reproduce the log file issue. Is there anything else you configured? Also can you check via the webterminal what the permissions of the log file in question are?
