litter training

My rabbit was free roam at my old house and never had an accident, i just moved to a new place and currently shes only free roaming in my room but shes having a lot of accidents which is unlike her. Should i put her in a cage till shes litterbox trained again? or is there another way?

Is she peeing in one specific spot, or is it anywhere?
It could be she's just settling in and marking new territory, but if she's always peeing in the same spot, you can try moving the litter tray there to encourage her to use it.
