My FB page is also linked to my Twitter a/c but I'm not having any difficulty with it.
Have you tried the help menus on either site. I'll have a look and check back in with you in a while.
I have mine linked and it seems to be working off and on. I'm not sure if it's a Facebook or Twitter issue. Last week Facebook went down for a good portion of the day, so I know it was a FB issue then. I'm guessing this week it might be a Twitter issue as the rollout of the New Twitter may be causing some burps. Sometimes if the Twitter API is busy or overloaded then posts coming in from other applications or platforms will not go through.
Ok thanks to both of you for responding....it looks like I'll just have to be patient until Facebook or Twitter fixes it. I use Hootsutie at the moment to post to both and will continue to use it. I just wanted to try something new to see if it would drive some additional traffic to my facebook page
