The API Output Console says: The sandbox attempted to start but no scripts were found for your campaign. Don't worry, this is perfectly normal since you probably haven't created any yet. Just write a script in the box above and click "Save Script". That is most definitely not true. I have several scripts, which have been running fine for months. Suddenly none of my scripts are working. I can open, edit, and save them, but nothing changes. What's going on? How do I fix this?
