Hello, I'm trying to send some funds to an address from my wallet, but I keep getting: -32603: -22: TX rejected: transaction XXXX tried to double spend coins from transaction YYYYY. Any tips on how I could track what happened or how to fix this? Thanks.
You'll need to make sure you are running the latest version of dcrd and dcrwallet and that you've resynced everything from scratch. Guide here: https://forum.decred.org/threads/how-to-rebuild-resync-wallet-successfully.1338/
