This is a continuation of this thread, as the topic has actually changed. I was able to restore the data as of last night, 21:00. (I'm still quite a bit shocked that ISPConfig did that to me....!) Still, the "bad" entry in the dns trash can remains. I allowed myself to take a look at the mysql database, and the record(s) that seem to have confused the whole system appear in these tables: del_status, dns_nodes and isp_isp_web, each with one occurrence of the domain, the latter being a whole web site with status "d". Can I just delete those three records so that the problem will be gone?
