1. Did you make an update of your database before upgrade?

2. If you revert to 4.3, can you then see your data? (Might not be possible due to database updates during 4.4 upgrade - make sure to backup before trying.)

I test in 4.4.11 (again)

With a soimple survey, import activate

Crypted data in
- Response view
- Response browse
- Response edit
- Response export

I don't know where have not crypted data , it was OK in 4.3
I reopen bugs

Hello,
was there finally any solution? Same problem, as long as not finalized the data are visible. As soon as the questionnaire is finalized the data are encrypted and not readable any more.  Version 4.3.3+200707

Uh, please update to latest LS5 version and try again.
