Can't save: The base64 data of the GeoGebra applet must not be NULL
Hi, I just spent a long time putting together my first attempt at a Geogebra activity/worksheet, only to get the bafflingly unhelpful error message above when I tried to save it. I think you can see my empty project here:
When I tried to download it in the hopes of salvaging something, I got this, and when I clicked Back my work was gone.Error We're sorry! An error occurred while you were using GeoGebra. Please try again later and let us know if your problem persists. One of the following things has gone wrong:
