I'm happy that you use this fliplot project, but this project has reached its end... I'm sorry :(
I (the author) finished my profession as an engineer, and I will be Jesuit priest. :)
What could you do?
Fork it and develop it. It is just code, Feel free to develop :)
Create your own pythonanywhere.com account, clone and start the server there. (Note, that my https://raczben.pythonanywhere.com/ account wont be refreshed...)
I suggest to checkout wavedrom/zoom, which is a similar, and more professional project.
