Just tried sending BTC to my exchanger from my Blockchain.info wallet, and got this error:
Validation Error: Error #-26: 258: txn-mempool-conflict
What on earth is this junk? First time I ever encountered this, and I have no idea why it's happening, or what it means.
Has anyone else experienced this, and how did you guys fix it?
I don't know what exactly is causing this error. Are there any unconfirmed transactions? Searched the net and there are a few similar complaints, all were reported this month, but no solution apart from contacting blockchain support, but there customer service is a bit slow.
Alternative option would be get your private keys from blockchain and import it to Electrum wallet or Mycelium.
