I wish I could help you but you simply are not giving enough information to figure out what is going on. WTFs definitely are not a high humidity frog so when you say the humidity is right, just what do you mean? When you say you got it recently, does that mean a week or a month? What is the habitat like (photos can be helpful)? What is its size and how big are the crickets you are feeding? Have you read any of the thousands of care sheets out on these?
