Possible fixes, broadcast your transaction on localbitcoin blockexplorer (yeah they have one) :
https://localbitcoinschain.com/tx/send

All fine with your coins the problem is in blockchain mempool and to unblock need to send transaction manually to bypass the blockchain mempool.

Solution step by step:


Open chrome inspector in the network tab
Try to create a transaction and get "Validation error"
Open "Headers" of pushtx request and copy content from FormData, field tx: "You need that content"
Enter that transaction in form here https://localbitcoinschain.com/tx/send and click submit
You'll get transaction id and can check it in blockexplorer this transaction belongs to you and you need to wait when it will be confirmed
