check if the directory (in my Ubuntu based setup) /var/cache/zoneminder/temp exists and belongs to user www-data. This would be the same location of the directories "events" and "images". Make sure a symlink exists for the /var/cache/zoneminder/temp directory in /usr/share/zoneminder/www

i have this link
temp -> ../../../../var/lib/zoneminder/temp

pwd
/usr/share/zoneminder/www

I have had trouble exporting events when ZM's temp directory does not exist or can't be accessed.
