Before diving into what the issue could be: it will likely be resolved automatically in about a week, since we’ll then have the database restored. If you’re in a hurry we could look now, but perhaps it’s worth waiting for that?
Unfortunately I am using all these tasks as they represent different versions of the same task. Would it ok if I just copied the JS from those working to those not working since it is the same expect for the csv file and information about the session/instructions.
You could give it a go, just be sure to make a backup in case it just causes more issues. I notice in your profile you’ve had some issues discussed around the 22nd and 23rd of January. The tasks you’ve got now are from how they were at the 4th of January. Taking the same steps to solve them as you did around the 22nd could help?
But if you’ve got the option to wait a week, I’d definitely recommend that, since you’ll have the working versions back then.
Unfortunately that’s not an option as these are the tasks for the follow-up sessions. I will try to remember what I did before and backup my experiments just in case.
