    You must back up the wallet before doing anything. Don't lose the private keys. If you have your private keys you can re-install everything back anytime. Commented Jul 16, 2018 at 12:27

giving an error as ' fatal error please see error log' ... what is the solution to this problem.

Step one is to do as it suggests. The location of the error log depends on the platform (Windows probably %APPDATA%\bitcoin, Linux probably ~/.bitcoin)

If all else fails, just install some wallet software elsewhere and re-import the private key you carefully backed up for just this sort of situation.


It's possible that the blockchain data is corrupt, in that case you should delete the blockchain files on your computer and let it sync again. Might take a while though, as Bitcoin's database is quite large.
