I am now getting this error when trying to send funds:
Non-canonical signature High S Value.
I've never seen this error before and I have no idea what it means. It's been a while since blockchain has been running properly. Any of you guys know what this error means?
This must have been part of their upgrade, to use the Bitcoin Core 0.11.1 rules. Bitcoin Core 0.11.1 and beyond now refuses to relay transactions that use a High S value in the signature scripts. This prevents transaction malleability. Transactions using a High S are now considered non-canonical (non-standard) and are now no longer relayed. This must have been part of bc.i's upgrade.
