Thanks for reply but I still have the problem. I restarted blockchain again and removed empty blocks. Wallet looks good - staking is active, the number of the last block in my wallet is the same as in blockchain explorer. But today I have orphan again. And no any valid blocks from 15.10.
join slack or telegram give more details like ur dmd address so we can have a look if it is unusual behavior
orphans can happen special if u have a high latency internet low ammount of connected peers or computer time not accurate
