Dear Prolific Community,
I have been experiencing this bug for a few days now. I contacted customer support, but they have not replied back to me. I am getting a bit desperate as I really need to launch the study.
I would like to exclude participants based on their participation in previous studies. I have run similar studies on Prolific, so it is absolutely crucial that I get to exclude them from participating in the new study to minimize the demand effect. I checked to make sure that all studies are ‘completed’ (or at least appear so on my dashboard).
However, when I tried using the ‘exclude participants’ feature, Prolific keeps giving me the error message.
I also tried excluding participants from creating the ‘block list’. Yet, it keeps recognizing a space, when there isn’t any. I double/triple-checked my participant list using the search/replace function on excel, notepad… everything.
If anyone knows how to fix this bug, please please let me know.
