trying to broadcast offline signed transaction, but got this error "The transaction was rejected by network rules. (16: mandatory-script-verify-flag-failed (Script failed an OP_WQUALVERIFY operation))". Electrum 2.8.3
Did you copy and paste that error? or type it in manually... because it should be OP_
EQUALVERIFY.... not OP_WQUALVERIFY
If it was copy/paste... Did you accidentally modify one of the transaction files while you were moving things around?
