We have an old web app that uses Facebook login, that now doesn't work anymore.
We need help to review our current code to find any errors it might have.
Your work is to review our public web app and suggest edits to the js-files.
You can receive the URL of the web app in a private message.
We are also using the FB php SDK in the backend, so the problem might also be there. But right now we are confused about where the problem is.
You won't get access our code repos or our servers.
