iPhoneLocator, worked for a day, now 2 phones report "Error executing function iphone_Settings(): names is undefined"

I am seeing this error when trying to access the settings of a phone setup with iPhoneLocator: Error executing function iphone_Settings(): names is undefined
It worked for about 1 day, and 2 of 3 the phone are experiencing this. All 3 phones have different iCould logins.

Despite this, the location seems right yet the battery level is stale. However, I can’t say for sure until someone leaves the house.

I try to set “debug” on, and it doesn’t stick.

I am using what I think is the latest version: v2.51

thanks
