Failure to launch sample in Pavlovia

URL of experiment:

Description of the problem:
To make sure Pavlovia is properly setup for experiments I was uploading various demos and attempting to launch them. The GoNoGo runs locally (hangs at the end, but otherwise works). It uploads to Pavlovia. It attempts to launch, but hangs on “initializing”. I am not great at troubleshooting yet.

It is probably not a permissions issue (tried multiple computers as one has had firewall problems) or a browser issue (“Explore” pre-uploaded public Pavlovia experiments work online). The experiment does not run locally using PsychoJS to launch in a browser (same hang on “initialising”).


your experiment has to run locally first until its very end. It won’t run online if it does not run locally.

Best wishes Jens
