I'll be honest, I don't know what that means at all. I am a high school teacher (AP Stats and APCS). I am making some stats applets through Greenfoot and embedding them into my website. I have published several of them but am getting this error as of a few days ago. Thank you for any assistance you can offer.
In that case, you probably don’t use it.
Are you currently able to publish other scenarios? If yes, the problem probably lies somewhere in the code of your scenario. If not, then it might not.
3.5.3
Do you think that is it? It has worked before which is why I didn't think it was. I have tried another computer and even created another account. The only other thing I can think of is because I am on the school district network...
This is weird because greenfoot isn't blocked on schools networks, but you can test, did you try to send your scenario to a computer at home and upload it ?
