Stimuli not showing up online (worked before)

Description of the problem : An XAB task (where a stimulus X is shown, then AB are shown and the subject has to chose which was X between AB) is not showing the X stimuli properly and is instead showing the AB pairs directly.

It works offline (meaning the X appears as intended). This is an old experiment that we decided to split into two and used to work flawlessly online.

I have verified the name of columns and they all add up. It really is just the X that is inexplicably not showing up.

I also tried playing around with the versions and rolling back to the version used by an experiment that currently works online using the same XAB task, to no avail.

Looking at the console showed man warnings but none that were exclusive to the X stimuli (meaning, there are warnings in the console for X, AB and other images that are shown, such that it is difficult to pinpoint a source of the error, especially considering the same experiment used to worked online and is working offline).

Thank you so much for your time!
Nicolas.

Hello

Which PsychoPy-version are you using?

Hi!

The tasks work correctly in other experiments using 2024.2.1 to 2024.2.4.

I tried switching around the versions (from 2024.2.1 to 2024.2.5) and can’t get the task to work on this new experiment (even though it works just fine elsewhere).

Hello

You might still run an old version from the brower‘s cache. Did you try an incognito window?

What are the warning/error messages in the developer‘s console?

Best wishes Jens

Hi! Thank you for your messages but I am confused by your remarks : they were all directly addressed in my original posts…

Never the less, while rolling back to 2024.2.1 did not work previously, re-trying it made it work again.

We think there is something buggy going on there that is not on our end, as we have the same task working and stuff.
