You can't. There was a "hack" some time ago. But Blockchain probably removed the entire "sign message" feature and it's not working anymore. You will need to export your private-key and sign them from a different software (e.g: Electrum);

Try to export them by following this guide: https://github.com/OmniLayer/omniwallet/wiki/Exporting-Private-Key-from-Blockchain.info-and-Importing-to-Omniwallet.org

In case you're using an imported address on blockchain.info's wallet, you can sign message by doing the following steps:
SETTINGS > Addresses > Scroll down and look under "Imported Bitcoin Addresses" > Find the address > Click "More Options" >Choose "Sign Message".
If you're not using an imported address there, then simply follow "TryNinja's guide".
