Addressing the new Space creation issue.
So there seems to be an issue with creating a new Space, where it is replaced with an error stating that a connection to the database could not be established. Existing Spaces, however, are not affected by this.
From looking at the error logs, this is an issue with WordPress attempting to access tables that have been magically wiped away from the database for some reason.
I’ll see what I can do about this, and hopefully it can be resolved within due time.
