I just went on facebook for two seconds before seeing a link posted by a page that I am a fan of. The link was pointed to another page that the person likes. The thing about this link is that it contained two links in one. Link one is the page that the link is ment to be, link two is a photo that the user was looking at before browsing to the page that he wanted to link. To activate that link you just have to remove that last part of the link, everything after the # symbol and including the # symbol.
To fix this. before linking to anything on facebook, press Ctrl+R or the Reload button on your browser, this will get rid of what you were looking at before, now you are able to copy the URL and use it as you like.
P.S. I have to get off the computer now because a thunder storm is passing through.
