Hello to everyone,
I have read some topics, but I still don't have very clear ideas. Yesterday I open a old electrum wallet (3.3. Cool

to send a little bitcoin part to other wallet, but due to an error in entering fee the transaction is unconfirmed.

Which is the best solution to unlock it?

First, you should not use old Electrum version 3 and better update to latest version 4.1.2 from official Electrum website.

Second, there is nothing to unlock here, but you can can read THIS guide for canceling your transaction or changing your fee.

Always check Bitcoin mempool before sending any transaction, and now 5sat/bytes you used is not enough for confirmation so you can either wait for weekend or use higher fee.

Thank you. I have updated electrum to latest version. I have select "Increase fee" and this window appears, could you help me?

Thank you again
