"Failed to connect best block" error when I try to load my wallet Everytime I try to open my wallet this error comes up. I have  shut the computer down   a few times  and  removed the wallet and reloaded it a few times too and the error keeps happening.



If you can't see the picture, it is a error message which says "failed to connect to best block"   and  it makes the wallet not open.
