Hi I have followed the installation guide and got lime survey working fine, however when I try to use it to QueXML export nothing happens, it seems like the script is doing something and then takes me to a blank page, instead of offering a zip file download like the demo did on limesurvey.org
admin/admin.php?action=showquexmlsurvey&sid=35987 just takes me to a blank page.
I have increased memory limit to 128M and I have enabled the pdf export in config.php I can export to xml file and use that to generate the pdf. However I can't get the QueXML export working. Any ideas greatly appreciated.
