Has anyone had a student who gets an error message that they must load an HTML file before accessing the lesson? I tried on separate computers to make sure it wasn’t an issue with her computer. I think the html file got deleted somehow but I can’t figure out how to get it back. It won’t let her add it.
Can you submit a bug report using the menu at the top right corner of whatever project or level is giving these problems? That way we can better investigate what’s going on.
