Hi Elise,
I disabled DebugOff at demonstration links on the farm during the last update, as several issues that users faced proved to be detected by the debugger although it had been turned off while the project was still under development. The debugger is automatically turned off at the data-collection link though, making DebugOff entirely effectless on the farm
You can close the debugger while testing your experiment by clicking the cross button at the top-right corner of its popup window (and you can bring it back up later by pressing ctrl-d, by the way)
