1) Is the space bar set for staging in the controls? It may have been reset, check your settings and make sure.

2) Where are you staging from? Space bar staging only works in flight mode and not map mode as far as I know, unless that got changed in v1.9(.1)

3) What game version are you using? Any mods installed? Does the space bar work sometimes, rarely or not at all?

4) Does your space bar work outside of KSP? If not it could be the key itself that's broken and not the game. Does it work for other things in KSP, like typing names for rockets?
