White screen on LimeSurvey administration panel
Originally created by @sajolida on #16549 (Redmine)
Today I tried to update LimeSurvey from 3.5.3 (Mar 16, 2018) to 3.15.9 (January 14, 2019) and got a white screen on the administration panel starting from 3.10.0 (June 11, 2018):
What I did (with a few more trials and errors in between):
- Try to update straight to 3.15.9: white screen!
- Rolled back to 3.5.3: works!
- Bisected until I identified 3.10.0 as the first version with the white screen.
- Rolled back to 3.9.0 and updated the database.
- Updated again to 3.10.0: white screen again!
I also tried to:
- Have a look at the Apache access and error logs: nothing in there.
- Restart Apache: both
/bin/systemctl restart apache2.service
andsystemctl restart apache2.service
failed,systemctl status apache2.service
was not very informative either.
My questions are:
- How can I further debug this white screen?
- Could I have more such debugging permissions in the future?
- Is there anything to fix so I can restart Apache in the future (though it’s probably not the fix for this time)?
Assigning this ticket to intrigeri as a start as he’s the one who set up LimeSurvey, though this sounds more like a task for the sysadmin on duty.
This is blocking me for the VeraCrypt success metrics (tails#15977 (closed)) that are not so urgent but the last remaining bit of Sponsor_W.
