Hi @fabian_7019, Thanks for bringing this to our attention. I was able to recreate the error and we will get this fixed in the next version of Otter, 3.0.25, which is due out next Friday. This looks to only be an issue when there is only one raft repository setup in Otter. As a workaround, if you create a second raft repository under Administration -> Raft Repositories, you will then be able to create new folders in the default raft. The fix is being tracked in ticket OT-461. Thanks, Rich
