Hello,
In our last CATI studies we have encountered a problem: we found in the databases missing answers for questions that should have been answered. We had unique passwords in all of our studies (1 password per respondent). In order to find the bug, we tested both locally and online on the exact passwords with which we had problems and the all the questions appeared.
The variable sys_UserAgent - for the problematic cases - generally records this type of information
-"Mozilla/5.0 (X11; Linux i686; rv:7.0.1) Gecko/20100101 Firefox/7.0.1"
or
-"Mozilla/5.0 (Ubuntu; X11; Linux i686; rv:9.0.1) Gecko/20100101 Firefox/9.0.1"
We are using SSIWeb v7.
We believe the problem might be between the current SSIWeb version and the software used, but we didn't manage to find the exact problem.
Did anybody else encounter this problem?
Thank you,
Dana
