Contact support...you probably now have ownership issues. Can you determine whom the owner of /home/elisenp/subdomain is? It should be 'elisenp' of course, but in the event it is not, support can fix that.
Each directory or file has an owner. The owner gets to decide if others in the same group or in the public can have read, write, execute permissions. The default permissions for directories is 755, where group or public users cannot write (create directory entries: create files in the directory) but the owner can. So most likely /home/elisenp/subdomain is not owned by elisenp, or perhaps it is but the permissions are not 755.
