Hey everyone.  So...I upgraded last night from 0.17.0 to 0.17.1.  The node seems to be working fine and I have plenty of connections.  However, my wallet is no longer displayed!!!  I've never seen this before and have no idea how to fix this.  I would appreciate any help since this is obviously a bit disturbing.

In the past, I've been able to simply display the wallet without the counsel window, command line, etc.  But I've never seen it display like this.  There is no list of my transactions and I can't see how it's possible now to send and receive BTC.

Please help:)  Thanks everyone!

Ok, There are 2 things we'll need to check here:
1) is your wallet completely sync'ed
2) is the wallet.dat correct

OP: are you using the QT gui, or are you using the console? Which OS are you using?

If it's the QT gui, there should be an indication at the bottom telling you if your wallet is sync'ed, if it's the console, try "bitcoin-cli getblockchaininfo" and compare the height with the height you can find on a block explorer (like https://www.blockchain.com/explorer).

IF your wallet is sync'ed, go to the bitcoin home folder (in linux ~/.bitcoin) and COPY the wallet.dat (copy it twice to several media, just to make sure). Once this step is finished, you can try to rename wallet.dat to wallet.dat.backup and put a backup of your wallet in the bitcoin home folder... Then restart and see if it fixes your problem.

IF not, try to start bitcoind or bitcoin-qt with the -rescan parameter.

If this doesn't work, you can always post the content of the debug.log so we can have a look at it.

If everything else fails, you can try to export all private keys of all funded addresses and import them into a different wallet.

Last but not least: as long as you have your original wallet.dat, you have the private keys (or master private key) you need to controll your funds... Everything else is less important... You just need to make sure you have your original wallet.dat, everything else can be fixed

Thanks!  I'm not at home now, which is where my node is running.  I'll check these steps later and let you know what I find.  In answer to your questions...

1. I'm running the node on an iMac Retina.

2.  I think I remember last night reading "Bitcoin QT" which I don't believe I've ever seen.  That seemed strange to me.

Also, in the bottom right there is no longer any display indicating that my wallet is password protected.  That icon is gone now.

Anyway, I'll work on your suggestions later and let you know what happens.

Not seeing the "encrypted"-icon (locked) at the bottom worries me... If your wallet.dat was encrypted before, it should still be encrypted after the upgrade.

Not to make you worried, but do you have a backup of your wallet.dat?

I do have a backup of the wallet.dat file. In fact, I back it up a few week ago and have it on a USB stick!  Sounds like that's a good thing?

Also, not sure if this is relevant, but last night I tried to set up a lightning node. It didn't work.  Any chance that could have something to do with my problem?  Difficult for me to know whether this problem is due to my upgrade process or the attempt to run a lightning node.

The fact that you have a backup of your wallet.dat is a lifesaver. It means that, if everything else goes south, you'll still be able to start fresh and restore your wallet afterwards.

I run a lightning node myself (bitcoind-clightning), but iirc, the "normal" setup process should cause no harm to your wallet. That being said, if you messed up, you could mess up loads of things accidentally

Man, I'm so glad to hear that having the back up is a life saver.  When you speak of "starting fresh" do you mean I'd have to download the entire blockchain again?  I can obviously do so, but I'd prefer not to.  It took quite a few days the first time  Wink

Thanks again for your help!

If your HD crashes, if your house gets on fire or even if aliens abduct your PC, regardless of what happens, if you have your backup you can recover your wallet.

You don't need to download entire blockchain as long as Bitcoin Core don't mention that your node is "X years behind". Since Bitcoin Core 0.17, you can use -wallet=<path> on application startup parameter path as well.

Okay.  Just got home.  I took a screen shot of my node display.  Is there a way to attach a jpg to this?

So, I just shut down bitcoin core and when I reopen it I get this message...

"Welcome to Bitcoin Core."

As this is the first time the program launched..."

Umm, I've been running this or over a year. 

I went into this folder ~/Library/Application Support/Bitcoin and found my wallet.dat file and a bunch of other folders.  I assume the blockchain is still on my HD.  Is that correct?  Anyway, I would really appreciate any help as I'm not a technical person. 

Also, is there a simply way I can just restore from my wallet.dat file?

Thanks again everyone!

Replace your backup wallet.dat with the new one created.

Um, I think you mean to replace the new wallet dat with the backup the op has on the ub stick.

Thanks for the advice Rickorick!  For now, I think I have a bigger issue.  My core software won't even open now.  Keeps getting locked up. 

Any advice would be greatly appreciated.  I can even copy some of the debug log if that would help you guys see what is actually happening on my end.

Seems like there's no problem with the block height (sync), since you've just updated, that warning occurred because there's something new to the network rules.
Looks like a firewall/antivirus blocking or connection error to me, try to temporarily turn off the firewall or create an exception for Bitcoin core.

By the way, do not follow Rickorick's suggestion. Obviously, it will overwrite and delete your backup!

Those errors don't explain why his wallet isn't displaying.

For those errors : 1st is just another node failing, not on your end since we can see you connect to the rest of the nodes. 2nd warning is just about the different block version. Some miners still don't support segwit, so the blocks they mine have an "unexpected" but compatible version.

Short answer : your node is running fine.

Debugging : do you know an address from your old wallet? Open consol and type : dumpprivkey (youraddress) to check if your wallet is still the same.
Fear missing coins? Write getbalance in the console, see if your funds are safe.

If your money is fine, this is probably a visual bug. I just read the patch notes for .17, https://bitcoin.org/en/release/v0.17.0#known-issues

I quote :
Quote
The GUI suffers from visual glitches in the new MacOS dark mode. This has to do with our Qt theme handling and is not a new problem in 0.17.0, but is expected to be resolved in 0.17.1.
You'll just have to wait. Don't panic!
