We've been using our Drupal webforms for years. Suddenly today, if an authorized user or the admin tries to download the results, the resulting file is 0bytes. The data is definitely there. I am unsure how to even troubleshoot this problem.
The really odd thing is that my dev site is a near identical copy of the live site and it works on the dev site (but the results are outdated). Whatever changed on the live site would have been in the last couple weeks and I can't think of what may have caused it that I wouldn't have implemented on the dev site first.
Drupal 7.50 Commons, webform 7.x-1.0. Let me know what other information would be helpful to provide, thanks!
Things I've Tried, to no avail:
- downloaded the results into different formats
- downloaded results as regular staff and admin user
- downloaded only final and non-draft results
