When setting UPS service and saving, a message shows some error:
"[monpwd] Empty value not allowed More info..."
point 1 : the message itself is not 100% clear but we can understand that it is about monitor password that is mandatory (in my case I keep the default empty) .
May be a clearer message can be set
point 2 : in the interface display, there is no star "*" after the description "Monitor Password" (for " Adding a star may alert that the " is also a mandatory parameter.
