currently getting this while trying to get into Viking Clan. I also play Pirate Clan but that one's working for me. ah, finally working again. nvm!
When that constantly happens clear your cache and cookies in your settings on your browser usually does the trick and if it doesn't use the offsite version of kano http://fb.kanogames.com/pirateclan http://fb.kanogames.com/vikingclan
Hi Andrew, If you get it again, can you post what browser you're using (and version if you know), where are you located, are you using https on facebook or http? Thanks!
