The most common reason links to other FLM pages sometimes don't work for some people is that the link is for first-loves.com, but you are logged into www.first-loves.com.
When you log in, your login info gets saved in a cookie which the browser sends on every page access on http://www.first-loves.com but it does not get sent when the link is on first-loves.com without the www. Thus the board doesn't think you are logged in and you get a blank page.
The solution when this happens is to add www to the the link, and voila!
