HELP! Can't upload materials to GeoGebraTube!
For unknown reasons I cannot upload the attached ggb file in the past few days! I see the message "An Error Occured: Application error" after I choose the file (in Google Chrome). I try to use the Firefox, then I can go to the next pages to enter all other information, but still get the same error message finally!
I have tried to use different computers in my home and in my office but I still cannot upload. I have tried to upload other files which I uploaded to GeoGebraTube successfully before, and still fail. :(
Can any administrators of GeoGebraTube help?
