Imgur

Discover the magic of the internet at Imgur, a community powered entertainment destination. Lift your spirits with funny jokes, trending memes, entertaining gifs, inspiring stories, viral videos, and so much more from users.

And in logs i see this error

 node_redis: Deprecated: The ZADD command contains a "undefined" argument.
 This is converted to a "undefined" string now and will return an error from v.3.0 on.
 Please handle this in your code to make sure everything works as you intended it to.

How fix it?

That's not a Redis error but it does appear to be a bug. Open an issue on Github.
