Redis::CommandError: MISCONF solved!

If you ever get this error with Rails and Redis:

rails aborted!
Redis::CommandError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

You might just need to restart redis.

If you’re using brew:

brew services restart redis
