Hi !
I already did the same procedure (submitting the files...).
I just updated to the newest version (limesurvey3.14.6+180821.zip).
Same issue

I recorded a short video to demonstrate the bug:

Hi all,

I just disabled the ajax mode in the theme. -> same issue

I also cleared the browser cache.

It is weird because with a short test survey, it's working. I send you the lss file per private message
Edit: doesn't work per pm... My complet survey is here..

To me it looks like issue, which only occurs when the privacy screen and the additional language switcher is part of the game.

Try to just answer the first two screens of your survey (without switching anything) and then change languages all the time (the next few questions). I have the feeling that the issue is not happening there anymore. But still to early to call.

I also can't reproduce the bug always... (see the video some posts before).

I agree with you jelo. But it must work for the first screen. The other solution is to have 2 survey, one in English and one in German.

Yes, I think jelo is on the right track. The language switcher is supposed to reload the page in the new language but if the privacy checkbox is not checked, that that is being prevented from occurring. The submit triggered by the language switcher should be independent of the privacy statement.

It's true that, if I switch the language with the privacy checkbox checked, it seems to work

juppix, can you tie the problem to whether the privacy checkbox is checked or not?

Yes! It seems that everything works well if the privacy checkbox is checked (always).
If I switch the language without checked checkbox the error appears.
