Not allowing commenting again Puntuado con 4 de 5 estrellas

It was working fine, then couldn't comment, like, etc. Did the temp fix of changing to keep and all was fine again. Today after it updated to 4.9.15 it's back to giving the Red Error, Try Again Message and can't like. I checked and the setting in config still says Keep. Do I need to change that to something else or is this a new problem with the new release?
