Hi @asmecher,
This error appeared for the first time only in php error log and since then I havn’t noticed this again. Yet, I was thinking this error happened during the submission process by the user. So, I tried to make a new submission but I could not reproduce it during the submission process.
As of now, I have no clue what caused this error.
Thanks for your support.

Hi @seisense,

OK; please keep an eye out for it to happen again, and post here if you’re able to determine something about how it happened.
