There are tons of discussions on forums and reported issues on the subject matter, and we know how to troubleshoot this. However, the persistency of this error popping up now and then makes me to file this request - can we finally get rid of this problem once and for all? All that it takes to get this resolved is to make sure Virtualmin removes traces of deleted virtual server (domain) from everywhere in the system!
Had this today again:
