I’ve downloaded Quelea for Unbuntu, typed in four songs, dragged to the service schedule section, clicked save as, named Jan10, then get a popup that the schedule cannot be saved. Why??
Since this problem has not been addressed by users with more Linux experience than I have, I’ll take a shot at covering the basics. The location of the saved schedule must have full read, write, and probably executable permissions. The default location may not have such permissions. Did you try saving the schedule elsewhere or modify the schedule location?
