Why am I getting a message quoted in the subject line on my Droid Turbo?

Invalid key secret pair passed. (data)

At random moment I receive the message quoted in the subject line on my Motorola Droid Turbo. Did it from day one and I've had it for about a week and a half. Does anyone know what this means?

Some info:
Had data transferred from old phone (droid maxx)
Most noticeably pops up during texting when my keyboard is open. Sometimes clears the text typing box.
I've disabled many apps (none I find relevant to texting) to speed up the phone.I get the note saying some apps may behave differently, not sure if it is related to texting.
I'm using message+

Quick Google search says it's ususally caused by either security software (Norton) or some Sleep Cycles app. Clearing the cache for that app should do the trick.
