When trying to log on with FB, i get this:
Error code: 8010
Error message: “Invalid appsecret_proof provided in the API argument”
I use the same code as previously, but now I get this error. There is no problem with the FB login itself, it’s just when I call backendless. I read this thread:
but I do not understand how this became an issue with backendless now when my code has worked this far. What is an appsecret and what does it mean that it is invalid?
