@wayne-workman , Thank you for clarifying. After some confusion I finally managed to resolve this on my test hosts. I will now replicate the change on my original environment. (My database knowledge is to blame).
Maybe if I ask nicely, we could request that this error be made a little more intuitive within the interface? (The error statement itself caused a slight offset within the interface, which is corrected after fixing the error)
(Again, I blanked out the IP)
