Hi,
Im trying to sign a message but get this error:
"Cannot sign messages with this type of address."
And if I try console command I get this error:
"AttributeError: 'Wallet_2fa' object has no attribute 'sign_message'"
What can I do?
Ive used my Electrum wallet to participate in an ICO, and they demand to sign a message for distribution

Following error has been discussed several times on/off bitcointalk.Had you read their documentation,you'd get required help.Anyway follow this thread :
https://bitcointalk.org/index.php?topic=1149503.0 Worked for me,should work for you too.
Lock the thread once sorted.
I tried that and it works for encrypting, but I dont really know if signing and encrypting is the same thing, they're two different options.
