J jmar83 Regular Pleskian Feb 16, 2026 #1 Server operating system version Debian 10.13 x64 Plesk version and microupdate number 18.0.75 get that error message after deleting domain. why? ...but domain was deleted. (?) -> Maybe the problem was, that i've removed DNS CNAME (in fact, it was a subdomain as an own entry in domain list) BEFORE removing it from plesk!? thx for feedback(s).

J jmar83 Regular Pleskian Feb 17, 2026 #3 OK thx. Why the problem occurs when i want to delete a domain? Does not really make sense i.m.o...
Sebahat.hadzhi Community Manager Staff member Feb 17, 2026 #4 When you remove a domain name a lot of background processes are performed. It is hard to point out the exact reason for the error without further investigation, but commonly this could be due to missing log files, a misconfigured custom jail, etc.
