My mother-in-law and my mother are at odds. What should I do?

Although discord between mother-in-law and daughter-in-law is common, there are also close contacts. You are anxious about their disagreement, which shows that you are a very good woman. They should be happy to have a junior like you. You can tell the truth of both sides, tell the good things the other side has done for each other, tell the good things they have said, and add your own associations to make them feel good about each other, and then it's up to them. It may not be difficult to change your opinion slowly.
