I am assuming you are talking about bitcoin since you put this in the bitcoin section. If so, check blockchain.info, it is a working block explorer among many others.
If you are not talking about bitcoin, then this should be in the altcoin section.
Actually I am not talking about btc. I just clicked the Technical support as I couldn't find such thread in altcoins.
I will delete this one and try to find it in altcoin
thanks
EDIT: oops! it says that I Cannot delete the post.
