Try logging in using an email address instead of a username. There seems to be an issue if you change your username.

Now, I am also unable to log in because of this error. This error box shows.

Problem solved. I tried many solutions and I am not sure which one really solved the problem.
Briefly:
1- I registered in a new account.
2-Logged in using the website Pavlovia.org
3- Synced the experiment from PsychoPy.
4- Ran the experiment online.
