Stuck in Initialising Experiment + Unknown Resource Error when trying to run experiment on local browser

URL of experiment: Pavlovia

Description of the problem: Hello, I try to run the experiment online but I get stuck in initialising experiment.
I have removed the html folder as suggested by wakecarter.
Before I tried that I had another issue (see picture below):


I preload the 12 files before the beginning of the experiment.

Hello Tommaso

you might want to look here
and here

(scroll down a little bit until you come to Resource error).

I might be that you forgot to add the extension of the image burger in your preload-list. Files usually have an extension which you don’t seem to use here.

Best wishes Jens

Thank you Jens!
The extension is on my preload list I think:

I’ve also previously added the extension on the csv file



so when you finally call the image burger, do you call it with burger.JPG or burger.jpg? You have file called burger.JPG online?

Best wishes Jens
