Have you checked that all VF Pages and Classes are added to their Profiles? You can find that when you go to the profile and scroll down to the bottom. I hope this helps.

This can be done by creating a script using our API. The specific endpoint you would need to update the name would be: https://developer.box.com/reference#update-information-about-a-folder. However, you would first need to find all the folder IDs of the folders with the same name. Perhaps someone else might be able to provide more details on that piece!
