I'm seeing the same thing, no hashing/current shares from the bitcoincz page. (everything is empty basically) But my miners are hashing away fine. Thought it was me testing a new Raspberry Pi with new worker, but the old worker shows the same when hashing as well.

Question - I am going to be getting more hashing power and I could swear there used to be a place to enter in your hashing power (when setting up a worker?) in order to hash at the correct difficulty or something like that. Is this gone now? All I need to do is create a worker and give it a pw?

Thanks,
