Experiment loads, but can't start

Hey everyone,

So, I uploaded my experiment (it’s a pretty classic LDT, just some visual word and nonword stimuli), but after it loads on Pavlovia I can’t run it. I am getting a 403 FORBIDDEN error when I try and run the experiment.

EDIT: I’ve updated this post several times as I learn more about the problem.

I noticed that I’m getting this error message when I try to push the experiment through Gitlab:

Pushing files to PavloviaTraceback (most recent call last):
File “C:\Program Files (x86)\PsychoPy3\lib\site-packages\psychopy\app\pavlovia_ui\”, line 470, in syncProject

git.exc.GitCommandError: Cmd(‘git’) failed due to: exit code(128)
cmdline: git push -u origin master
stderr: ‘remote: HTTP Basic: Access denied
fatal: Authentication failed for ‘’’

The problem is that the ‘new-ldt’ from the last line isn’t the experiment I’m working on. Actually, I have since deleted that project and I even deleted that Gitlab account (‘unagi_pie’). This is happening every time I try to sync a new project to pavlovia. Not sure what to do.

There seems to be an issue with creating a new origin and master, it keep trying to access a previous origin/master.

Any ideas?

I fixed this problem myself by adjusting my ‘credentials’ in the control panel. The password and username were set to my previous account on gitlab.

However, I am still unable to run my experiment. Every time I try to run it I get:

403 Forbidden

I’m not sure what to do.

Did you ever figure out the solution to this? I’m also getting “403 Forbidden / nginx” on an extremely simple test project, literally just a single routine with text and keyboard response.
