Pop up window while pilot study is running

URL of experiment:

Description of the problem:

I am running a pilot trial for my psychopy experiment on pavlovia, and everything runs well until it reaches this certain point of the experiment. Everytime I press a response key, a pop up window with an option to “leave site” will appear in the middle of the screen. I tried running it on safari and firefox and the same thing happened, so it’s likely not the server’s problem.

Does anyone know what went wrong? I can’t figure it out:(

Does this experiment contain this code?

webbrowser.open(weblink,'_self')

I have some studies where I’m not collecting full data and end on the slightly odd instruction “Click Leave in the popup to continue”.

If you want participants to open a link and not leave, then you need

webbrowser.open(weblink,'_blank')
