Is there a way to sign a message using the new Blockchain.info wallet? In the old version it was quite easy. But in the new version, they seems to have removed this functionality. Actually, this is quite frustrating.

You can't sign messages with addressss created in new Blockchain.info wallet. If you have imported private key or if your addresses were created in old Bloclchain.info wallet, you can sign messages. If you want to sign messages with addresses created from new Blockchain.info wallet, you will have to first get private key of that address from seed (aka 12-word recovery phrase) and then import private key to a wallet or use a program only for signing messages.

I am also facing the same problem, as I can't sign messages with the new Blockchain.info wallet. How to get the private key of this wallet? I have the 12-word recovery phase with me (written down in paper).

Download https://github.com/iancoleman/bip39 and open it. Enter your 12-word seed (aka recovery phrase) in "BIP39 Mnemonic". Scroll down and you will see your addresses and private key corresponding to each one. Import private key of the address you want to sign with into a wallet such as Electrum, Bither or Blockchain.info or use a tool like https://github.com/weex/bitcoin-signature-tool. If you want to sign message with a "change" address, change '0' to '1' in "External/Internal".

I was able to sign an address using this method of yours sir.
Doesn't took long enough

thank you.

just to make sure. is this what signature looks like?

-----BEGIN BITCOIN SIGNED MESSAGE-----
This is julerz12 of bitcointalk.org signing this address: 1KQrcHGoo2KFNFvnkYExxJY8TUJXFgJ1QR as proof of ownership on 7/20/2017.
-----BEGIN SIGNATURE-----
1KQrcHGoo2KFNFvnkYExxJY8TUJXFgJ1QR

-----END BITCOIN SIGNED MESSAGE-----

Also, I picked that address ( 1KQrcHGoo2KFNFvnkYExxJY8TUJXFgJ1QR ) on the very top list of generated addresses.
('cause there seems to be alot of addresses listed when it was generated ) won't that be a problem?
I used the BIP39 Mnemonic i had on blockchain.info.
