      There is no provider library and wsrep_on is disabled but a FK check is still logged:

      2017-10-02 14:52:49 140269844322048 [ERROR] InnoDB: WSREP: referenced FK check fail: 15 index user_class_ibfk_1 table XXXXXXXXXXXXXXX
      

      All Galera checks should be disabled when wsrep_on is set to off.
