Hi mlarcelet,

That is interesting. Suggests it might not just be my issue alone.

Tell me about: "Had to restore my install from my backup"

I'm guessing if I don't already have a backup, and I guess I'd know this, then this option isn't open to me.

I confirm this (tried the update twice)
- The changelog was blank ;
- a warning said that the version.php had been modified manually (i didn't)
- The pb appears after proceeding to step 3 --> result in a blank screen

@mvdct:
I perform a daily backup of the limesurvey database and the limesurvey web app folder.
I restored my database from the auto backup that LS performs just before upgrading.
I restored the app from my yesterday's backup.

Hi mlarcelet, thanks for skipping in. So we have 3 cases with problems already and you could even confirm the version (which I assume will be the same for mvdct). I am running v131206 right now and after reading this I will NOT update of course. ;-)

Would you be able to make a bug report, because with 3 cases showing up here, confirming that Limesurvey was running fine before, there is a good chance that this is a bug.
Have a look at the manual! It is a really valuable source for information. Here some helpful links:

@holch - Totally agree. It looks like there is a bug.

@mlarcelet - That sounds exactly the same as I experienced. Useful to know. Are you OK submitting the bug report, or shall I? I'm happy to do so, but haven't submitted one before. Just let me know.


...on a slightly more personal level. Does any one have any idea how I can get my own install of limesurvey back up and running ASAP!?

Did you check if your server has PHP 5.3? As Iscar says, this might be the problem?

Thanks holch.
Is iscar saying "5.2 good, 5.3 bad", or "5.2 bad, 5.3 good"?
My server is currently running PHP 5.2.
I can update if necessary, but I think iscar is saying: 5.2 good, 5.3 bad.

I think what he is saying is: LS 2.05 needs 5.3, but it would have been better to stick with 5.2 as it is a more stable version of PHP.

I had a quick look and Limesurvey 2.0 and later requires PHP 5.3, according to the manual:
manual.limesurvey.org/Installation#Make_...rvey_on_your_website

So here is my "translation" of iscar's post:
all problem caused by php version.2.05 need 5.3, it will cause lots of problem.5.2 is much much better, stable.
All these problems are caused by the php version. LS 2.05 requires 5.3, but this will cause a lot of problems. PHP 5.2 is much better as it is more stable.

@holch. Thank you.
So potentially upgrading to 5.3 could resolve this issue.
But might cause others in the future.

Upgrading my server from PHP 5.2 to 5.3 solved this issue.
Thanks to all those who gave their advice.

Dear all,
I had the same problem when using the comfort update to move from version 2.0x to the most recently available stable update. The update went all the way to step 3 (including the automatic backups) but then stopped with a white screen at step 4.
Now I can not access the installation (emmpty screen where the login window should be).
Downloaded and manually installed the latest stable version (205plus-build140116) from the Limesurvey Website following the instructions (including copying the Update folder and the Config file), however, when trying to log into the admin backend I get the same blank screen :-(
Database corrupted during update process???
Where do I find the structure and SQL database backups that are created during the comfort update process?
Any other suggestions?
THX Marcus
