E2280 Unterminated conditional directive (Delphi)

Go Up to Error and Warning Messages (Delphi)

For every {$IFxxx}, the corresponding {$ENDIF} or {$IFEND} must be found within the same source file. This message indicates that you do not have an equal number of ending directives.

This error message is reported at the source line of the last $IF/$IFDEF/etc. with no matching $ENDIF/$IFEND. This gives you a good place to start looking for the source of the problem.
