I am having the same or similar problem as Minisoapy.
I am using ISPConfig version 2.2.35.
For two domains (Which are now deleted and recycle bin emptied) there are straggling dns records which appear to be damaged.
The records don't show up in the dns list, however, I find them when I do a search.
They will not delete when I try to delete them. They never appear in the recycle bin.
Here's a picture:
Notice that the record does not belong to a folder.
If I try to set up a website for one of these domains, they don't resolve, so I really need to get rid of these damaged partially deleted records. The recycle bin is empty!
Thank you in advance for any information you can provide.
