Hi,

I received the error "The remote server returned an error: (400) Bad Request." when integrating with facebook login.

The detailed error message is as follows:

Can anyone let me know the cause of the problem. I am using DNN version 6.2.5.

Many Thanks

I have upgraded to 6.2.6 and am getting the same error on our site.

Well, the error stopped for us. Not sure what fixed it, but it persisted for some users until they cleared their browser cache.

We are now on DNN7 and not experiencing the issue any more.
