Hi everybody,
we are having a problem exporting the answers in some of our surveys in Excel and CSV formats, getting the error you can find attached.
We've noticed that this error happens only when we export surveys which have the "Save timings" option enabled (“Notifcations & data” section) - if this option is disabled, we can export succesfully in Excel and CSV.
We are using Limesurvey CE and the version is up-to-date (4.1.11+200316). In the past, using Limesurvey 3.X we managed to export successfully surveys with the “Save timings” option enabled in Excel and CSV. We are experiencing this issue after the update to Limesurvey 4, which we did in the last month.
