Hello,
I am having the same problem that was mentioned here (
www.limesurvey.org/component/option,com_...004/catid,1/lang,en/) but as far as I can tell was never resolved in that thread.
When I click on "Export Survey Structure", a page loads with the URL "http://{servername}/surveys/admin/admin.php?action=exportstructure&sid=58894" with the admin toolbar, the survey toolbar, the footer, and nothing else.
I have 1.70+ (4553) installed. All other export functions seem to work perfectly. I am running Windows on IIS. My old version of PHPSurveyor was able to export surveys just fine, and as I said, the other export functions are fine on this install too.
Thanks for any help.
