Hi there,
I have Loki setup on K8S
been using the Loki for a few days, now (suddenly) I get the above error ..

this is some output of helm get Loki command :

The error message is correct, as the configuration key does not exist (anymore). It has been removed renamed in #610

According to 3d3c057#diff-fdd086729867007e57c74aad7c391f90 it should be sufficient to update

loki:
  querier:
      max_look_back_period: 0   #the value is here!

to

loki:
  chunk_store_config:
    max_look_back_period: 0

@GuitaristForEver Can you try updating helm chart. You are currently at loki-stack-0.9.1, latest is loki-stack-0.9.4
That should solve your problem.
