I created a map in ArcGIS Online. It didn't let med put things from "My Contents" (or whatever the proper english name is) in the map. Instead, I had to upload the files directly to the map. Now it won't let me edit the map, it just says "Error loading the map". I still can see it in my ArcGis app, however.
If I try to create a new map by uploading the files once again, it says "Error" again.
So I wonder:
1. Why won't the map design window let me add things from "My contents"?
2. Why won't the map even open for editing after I have saved it?
3. Why won't the site let me uploadthe files to a new again?
ArcGis online seems incredbly buggy at the moment...there are functions like adding from my content, but nothing shows up even if I have uploaded the files. 
Or have I done somthing wrong somehow?
