[Solved] Facebook login always says "UniqueID is required."

K23

Hi all,
I've installed latest Vanilla version 2.0.17.10 on my own webspace. Worked fine. I've enabled Facebook Login. When I click on the Facebook-Icon the new window forwards me to Facebook. I confirmed access. But then the window returns to my Vanilla forum, saying 'UniqueID is required'. It also does not show my user picture from facebook. Here in the forum I already found a workaround with replacing some lines of the facebook class but this also does not help. What else could be the reason?
Thanks!

OK, please ignore this. With the help of this thread http://vanillaforums.org/discussion/15053/solved-problem-with-facebook-plugin-uniqueid-is-required-error I foudn out that there was a blank at the end of the SecretCode when I double-click it in Firefox. It would really be helpful if checking for whitespaces.
