[SR-Users] DB invalid connection parameter

Hi, Facing the following error after bumping Kam from 5.3 => 5.4 => 5.5 => 5.6, following instructions on each step about DB structure and module changes. These errors show up since. Any clue what they mean? A couple other modules are using the same DB MySQL connector. The data in the DB also seems to get updated properly.
