After move, category archives don't show posts

I know from looking through the forums that this is a pretty common problem, and I can understand people not really wanting to answer me. It’s probably the sort of problem that most people can fix on their own if they just guess and check for long enough, but I really do need help. I’ve already done all the guess and checking that I can. I’ve spent a full day on this, read every article on this topic that google had to offer, and nothing seems to make any difference. Please please please I am desperate for some help on this.
