I hope you can tell me again what is wrong.

I'd say: your hosting provider. :lol: Those "firewall" alerts just make no sense. :silly:

But here my bet: uploading files is forbidden in your system.
Now that you know it's not a bug related to LimeSurvey, but a hosting configuration problem, force them to solve it quickly.

Do you know this problem?
I think my hoster doesn't get this.

Ask your provider : it's a host issue, ask him to deactivate this dumb WebNight ....

Thnx all

My hoster solved the problem.

Great!

You're welcom. Also, next time, think about using the LimeSurvey Professional Hosting:
www.limesurvey.org/services#pricingHostedSubscription

It's made by LimeSurvey team, it will avoid you a lot of problems, it will give you access to premium support (via the ticket system), and it's a good way to support the LimeSurvey Project.
