* The facility's Crewlist has to be set to open to all
* The facility must have an operator and that operator must be active, ie: logged in within the past week. There is no limit on the number of facilities you may operate and no requirement to be at the same location as the facility
* The facility must have a manager, if they are a player they must be active. Note that some facilities require that the Manager be a faction of a certain type (see Section 4)
* The facility must be powered
It almost always an inactive player manager that I see causing this.
