I feel really dumb now, but where do i place "-walletbroadcast=0" ? In the launch option somewhere? But im not sure where.. Or the command when bitcoin ccore is open?
I guess this is the only way to make it unstick..
You can either run from cmd bitcoin-qt/core -walletbroadcast=0 , or create a shortcut of bitcoin-qt/core and add -walletbroadcast=0 in the end of the 'target' field.
