ERROR

[traore arouna]

Hello
I am here because I am developing an e-commerce application.
But at a certain level of my code when I run my server with the command
python manage runserver
I have an error message
Uncaught ReferenceError: info is not defined

Are you switching into your projects directory and then using 'python manage.py runserver' from command prompt/terminal to run your website?

I think the error is from the frontend javascript code. Can u share snippets of that code?

It is js error, show the script part. It seems like you referenced a variable before declare it.
