As the error code does not appear, this is undoubtedly a script error in your game. This happens only when using cheat programs, and ends up messing with some hexadecimal value that should not be changed. With this, when connected to the game version on Facebook the server realizes this script error and does not let you access it. This does not happen in the mobile app because the server does not do this when you log in there.

I'm not saying that you used such a program, but that's what happened in your game. As it is a script mistake so developers will not fix the problem for you, you should look for someone who understands game development and see if it manages to fix it for you.
