Electrum does not sign a message

[xxxgoodgirls]

Hi there, I am sticking with this problem which I can't get it out from.
I am trying to sign a message to prove the ownership of a given address but when I type in the message and the address and then click on sign I receive a blank text error.
I tried it on electurm both windows and linux version, with no luck.

Any hint? Thank you in advance.

what version are you using? and on the second box of the sign message window, does it say address or public key? if it says public key then you are on the wrong menu. nvm there's no sign button on ecrypt/decrypt tool.

I should be on the latest version, 2.6.4.
In the second box it asks me for an address, and that's what I am putting in it.
Another weird thing: when I try to encrypt a message it just lets me do it.
When I try to decrypt the very same encrypted message and address it just says me address not found.

Can the whole wallet be somehow corrupted?

it's not possible signing a multisig address (address that begins with 3.) with electrum or any other known wallets.

Ohhh thank you
How to proceed? I really need to prove the ownership of the address, will the bitcoin core wallet let me sign it?
