Needing HELP with new Tree frog issue!!!

[Minizoo]

Hi there,
My name is Erin and I am the new owner of an adorable Whites Tree Frog/Dumpy Tree Frog. She came to me unexpectedly yesterday when my aunt bought (paid for I picked her up) this beautiful girl as an early birthday gift for my son. She appears to be pretty healthy and the lady I picked her up from said she fed a couple crickets to Luna before I showed up but since bringing her home she isn't interested in the left over cricket in her enclosure (they keep escaping too lol) or any of her super worms. Luna is also hiding and has changed color from her beautiful bright green to almost a dark green or brown color. Any suggestions what might be causing this would be greatly appreciated. Her current temp is around 72.5°f and humidity is at 75% and it is 8:50 pm. I turned her light off to see if that made her more active but nope. Help please!!!!
