I've seen this reported before - it's failing to get campaign data from DDB.

Few things to try

1) Try joining from the campaign page - Make sure you're on the latest version - there was an issue after a ddb update not too long ago with getting campaign id. It may be missing the campaign id for some reason if something is changed again.

2) Try clearing cached images and files.

As long as you don't select cookies/other site data it shouldn't clear any abovevtt data but you can take exports to be safe.

You may have to restart the browser after clearing this.
