I have several documents uploaded for my students to access within my course. I know hot to upload and edit these pages/document with no problem. However, many of my students have been complaining that the documents uploaded last month no longer work. When they click to open the document it says "page not found".
I've tried deleting the document and then uploading it again-it works for a while-and then will do the same thing again. Our students have iPad minis-I don't know if that has anything to do with it or not. Can someone please tell me why these documents seem to "expire" after 2-3 weeks and how I can fix this? There has to be an easier way than deleting it and then re-uploading it again.
