I have been experimenting using a Facebook login button on my website. The login button renders correctly the first time I access the page and when I arrive at the page through a link, however, if I refresh using cmd+r in Firefox and Safari for Mac, the button does not render.
Does anyone have any ideas? An example of the button can be found on the homepage at – http://www.totalwindsurf.co.uk
Thanks.
If you are using the fbml version You could try to render the button using javascript, and xfbml parse.
