Ok this is really irritating. I don't get many fan pages but when I do the majority of the time they're not redirecting to facebook properly. Facebook says 'The page that redirected you here was not a facebook page' and won't give me the option to get to the page in question, so I lose any credits I might have got.
Is this a browser issue or something else? I just had 6 fan pages and out if those only one of them worked. Gutted.
