Im no blockchain expert but why am i getting this message and how to fix it?

An outpoint is already spent in 5c11d4f8fcfe19896dda4e6f22ab03903cf4555a501f2d7c89da546c8c54ff73

I have plenty of btc in my wallet and it doesnt matter what tx fee i add or what amount i try to send it wont allow any transactions.  FYI this is from a blockchain wallet if that helps anyone. Any help or explanation and fix is appreciated

Your wallet is trying to spend from an already spent output for some reason. This is usually a bug in your wallet software. You really should stop using blockchain.info.

Blockchain.info wallet has some disadvantages, recently > my friend wallet got hacked (don't know how)
what kind of wallet do you use for daily transaction, any suggestion?

That is the worst part of using this wallet, as there are so many issues pops up. Changing of wallet(except any web wallets) is the most recommended thing you have to do now.
