Conditions files not imported -> "unknown resource"

The experiment runs offline. All resources are uploaded to Pavlovia. But when I start the experiment online I get the following error:

Pavlovia

I also can see, when starting the experiment, that no resources are imported …

Does anybody have an idea what’s wrong here?

Thanks a lot in advance!

Have you attached your resources in Experiment Settings / Online?

Yes, of course. If the solution would only be that easy… :wink:

Are you (or have you) used an html folder with this experiment?

Yes … (is that wrong for the most recent version of PsychoPy/PsychoJS?)
