For some reason or another, my Heroku-hosted oTree has stopped allowing me to export "All apps" data. This is despite being able to export individual app data and pagetimes, and having not updated any code or code dependencies since last downloading "All apps" data. 

Is there any possible way to recover Participant vars from my postgres server? I have some data stored under participant that is very important and I do not want to lose it before resetting the database and (hopefully) fixing the export bug!

Thanks!

Hi spurl -

In this situation (if I couldn't use the logs to troubleshoot why the all apps data wasn't exporting) I would try implementing custom_export for the apps that had the participant data I needed.

Thanks,
