I suddently have a problem backing anything up or importing anthing from one course to another. I get the message "Couldn't delete previous backup ids" every single time. It used to work fine and I have not changed a thing since then. I'm the administrator of the system (a school system with around 800 users).
This is quite critical, so I hope someone has a solution. A search of "Couldn't delete previous backup ids" brought up nothing useful.
BTW, if I don't answer back it's because I very soon leave on a vacation. Would love to get this issue solved before then, but it is probably not realistic.
