 * I added a few of my subsites to a subnetwork, and removed them after a while.
   Once I remove them, I have database connection error to those subsites.
 * “Error establishing a database connection”
 * How to handle this problem?

 * It turned out that once I take out one subsite from a subnetwork, I have to reinstate
   that one to main network (or network no.1). It’s like the subsite has no network
   unless I do not reassign it.
