I seem to have the same problem, but out of 10 participants, 6 were not saved. The details are the same; I have a few rows per “missing” participant recorded in my results file, like so:
# Results on Tue
# USER AGENT: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML
# Design number was non-random = 8
# Columns below this comment are as follows:
# 1. Results reception time.
# 2. MD5 hash of participant’s IP address.
# 3. Controller name.
# 4. Order number of item.
# 5. Inner element number.
# 6. Label.
# 7. Latin Square Group.
All 6 participants submitted between 15:57 GMT and 16:17:47 GMT; other participants’ data was successfully stored before and after this point. Can this be attributed to a downtime episode as well?
Would minimising the data in submissions help prevent this, and if so, how would I do that? (I still need to collect 160 participants.)
