If you see "No Room of This ID" when you try to open your Space, you may have included spaces or special characters in the name of your Space. Your Space name is part of the URL for your Space, so it cannot include any special characters like spaces or \ , < , > , . , @ , ? , &, etc. and any character outside the ASCII charset.
In order to gain access to your Space, you will need to copy the Space, then use a name for the cloned Space that does not include any special characters. For instructions on cloning a Space, please refer to our article on copying a room or Space.
