Hi,
yesterday, after quite some time, I did a payment with the offcial client (not updated to the latest version, I was running on 0.13.2)

After many hours I saw I had no transaction confirmations.

I have then executed the bitcoin-qt with the -zapwallettxes option to remove such unconfirmed transaction.

Procedure worked flawlessly.

I then upgraded to the latest release 0.14.1, re-executed the same transaction and again no confirmations.

This morning I have tried to withdraw from the exchange I'm currently using and even for withdrawals I get 0 confirmations.

Any advice on what to do?

Thanks a lot.
