My INODES warning came up with a counter of 65878 / 80000 so I deleted the above sandpit domain from the dashboard about 10 days ago however the counter has not changed much.

When I look in the root folder I can see my 2 remaining domains (with their own htdocs folder) and a htdocs folder. Could this htdocs folder be the remains of the sandpit ?
