After several tries of downloading the latest version of the wallet and synchronizing it I have the same problem over and over again. The original wallet still shows the coins under Staking on the left and nothing moves for days, when using new wallet on another computer and locking the wallet during synchronizing as advised, it simply synchronizes, it shows transactions on the right until June 31st or under Transactions tab, but nothing after that. The issue is also that also all fields on the left of Overview tab stay empty after synch.
I have tried also removing everything (one including config file) with bootstrap file added and wallet.dat left, but the wallet doesn't open then.
Please advise exactly how to proceed (if I should use config file, what to copy inside and how to name it) to be able to continue staking and have a working wallet.
Make sure you are synced, then go to help > debug > console > then type "repairwallet"
Let us know how you get on, as there is another way if that doesn't work, but it takes more work.
This happens when you start staking before you are fully synced, the update that is due out shortly already has a fix for this happening in the future.
