Description of the problem: My Experiment runs on PsychoPy without problems, but when I try to run it on Pavlovia it doesn´t run. When I try it on Pilot it just creats a white screen. I have the new PsychoPy 2022 1.2. I tried it several times with new folders, but it never worked. The errors occurs: Failed to load resource: the server responded with a status of 404 () /Hauber/meditation/index.html/lib/psychojs-2022.1.2.js:1
Failed to load resource: the server responded with a status of 404 () psychojs-2022.1.2.css:1

I am really don´t now where the Problem is. Maybe somebody can help me. Thanks in advance.
The behaviour definitely indicates that at some point in the post you’ve had index.html in the output path field in Experiment Settings / Online. That’s the only reason for a folder called index.html to be created. I think you need to try recreating the experiment from your local files after first deleting the hidden .git folder.
I also have the problem that my experiment runs fine on PsychoPy locally, but it does not run online. It never surpasses the screen “initialising the experiment…”. I do not receive any error message, it just does not run. I am using PsychoPy v2022.1.2 on Windows 10 pro, and I tried running the experiment in Mozilla Firefox (with lots of addons) and in Vivaldi (a chromium browser, no addons).
I followed all the suggested steps, with the exception of not deleting a html folder, because I did not have one.
Then I tried again. It created a new project on Pavlovia.org just fine. I set it to “pilot”, then I tried running it from the dashboard and also from the “run online” button in PsychoPy. The browser tab always opens and gets stuck at the initialisation screen.
I was wondering whether this could be because we included additional python libraries via code? (Could be that we’re importing stuff redundantly, because we did so via several code elements at different places in builder.)
import numpy as np # whole numpy lib is available, prepend 'np.'
from numpy import (sin, cos, tan, log, log10, pi, average,
sqrt, std, deg2rad, rad2deg, linspace, asarray)
from numpy.random import random, randint, normal, shuffle, choice as randchoice
import os # handy system and path functions
import sys # to get file system encoding
import psychopy.iohub as io
from psychopy.hardware import keyboard
Any ideas on what I could check to find the bug are welcome!
