Private key has nothing to do with the Blochain being out of sync.
You need to click "SHOW" to see the private key look on the tutorial again you'll see, you should not click on private key as there is no link to click.
I'll get real simple for ya, since we clearly are not on the same page...
In the tutorial at:
https://steemit.com/muse/@cob/new-muse-blockchain-web-wallet-ready-to-go
There is a screen shot headed by
Once in Permissions, click the little key icon under Owner PermissionsIn this screen shot there is a red circle drawn around the "key" icon. The suggestion is you click on it, I KNOW this because it says "click the little key icon".
Except its not clickable in my wallet, which is unlocked.
I know how to obtain a private key, have done it many times, but cannot click through on the icon, as stated in my previous post.
