I've made a mistake and sent a transaction with low fees, and it's stuck for more than 24 hours in the mempool with 0 confirmation.
So I've started my bitcoin-qt with option '-zapwallettxes=1', and it cleared my unconfirmed transaction from my wallet.
Then I've sent a new transaction to a different address but with a higher fee (dynamically calculated), the transaction appears on my bitcoin-qt client, but if I search for its transaction id on blockchain explorers, e.g. blockchain.info, it says that this transaction doesn't exists.

Any help is appreciated.
Thanks in advance.
Can you see the first trnasaction in blockexplorer? How much sat/byte did you use (fee rate)?
Maybe you will have to have to wait a few days, but this first transaction will most likely be confirmed. I am making a lot of 1 sat byte transactions with no problems... 4-5 days at the most
