It seems I have the same problem than m0ufa:
On my DNSmanager, the recycle bin shows: "DNS Record: myweb.com", I empty the recycle bin but this record remains.
On my IPSmanager, I already deleted the myweb.com site and the recycle bin is empty but it shows "Note: Items remaining in recycle bin after emptying are currently in update state. Please try to delete them later." I have already wait for hours, there is no change. I tried to empty recycle bin anyway with no result.
The problem is I cannot recreate the myweb.com site: I get the error message: "The name www.myweb.com
is already in use by another site or domain."
Thanks if somebody can help with this.
