I've been running a few instances of empty question export files (0 bytes) upon use of "Export this question." However, importing the same questionnaires into the the Limesurvey Demo version leads to proper export results for the same particular questions, so that would seem to rule out a number of things.
Do any of you tuning into this post have ideas on what I should look into in my server environment? (Version 2.05+ Build 140717)
