Hi Rica1

It is a bit hard to reproduce this issue without further information. If I understand correct, this is happening when you try to view the maps in the administration, correct?

Does OpenSim have regions up and running? Is the database connection to OpenSim working? What is happening when you look at "user" in the administration?
