On any options-based question, if I go to edit the answer options, click the "Save as label set" button, and on the resulting dialog attempt to save it as a new label set, nothing happens. Also, the dropdown in "Replace existing label set" option on that dialog is always empty even though we have lots of label sets that were created when we hadn't upgraded Limesurvey from v1.92+ to v2.05.
PFA the screenshot of Ajax requests captured by Firebug for when I attempted to save a new label set.
Installation Details
Limesurvey v2.05
Windows Server 2008
SQL Server 2008R2
Uh, oh. Before we decide to update, I'll need to be sure on whether this is a known issue as our database is huge and upgrading requires several approvals.
Did you test against Windows/SQL Server environment? I have a feeling that this is a SQL Server specific issue.
