Problem uploading old file

Erik Espedal Boge shared this problem 4 months ago

I try to make an online worksheet from a file I originally made in 2010. I have reopened and edited the file today, and creating the actual worksheet with an interactive app works. But when I try to save it, it fails with the error message "This is no valid material: O:8:"stdClass":1:{s:5:"isNew";b:1;}!"


Should I recreate the file again, or is there a way to fix it easily?

That file loads OK for me in GeoGebra Classic 5. Please say precisely what you did to get that error

I created the file with Geogebra Classic 5.0.574.0-d (19 February 2020) and tried to share/upload the file.


The Error occurs when I try to save it online
