Can't change Theme in admin panel

[meiremans]

I copy paste the Cloth folder, in my own theme folder.

This shows up in the admin panel, however when i select it i get unkown error, check input on save.
The API responds with a 302 status.

Workaround for this is to set the theme in settings.json. this loads without problems.
