Error 500 when saving in "database" mode: is it okay to use CSV?

URL of experiment: https://run.pavlovia.org/Crible/causalrating1/html

Description of the problem: I’m having issues with Pavlovia since last week, the results are not saved in the database when the experiments are run online, but it works in “csv” mode. I have already posted about this but since I haven’t had a response yet, I was wondering if some people use the csv option to save the results of their online experiments, and if that works fine. I’m really stuck by this problem for my two ongoing experiments (never had this before) so I’m tempted to run them in the csv mode now.

This is the original message where I explain the problem, by the way: Pavlovia internal server error - results don't get saved

Thanks already!
