This transaction already has over 50 confirmations. Blockchain is reporting it as unconfirmed. Check it on another explorer:

Blockchain has become more and more unreliable. Don't reply on it too much. You should send some coin to other wallets, so you can at least send coins when blockchain.info is down.
Tell that to BitWallet devs. They use blockchain.info API.
To OP: lose BitWallet. They're a joke.
