I have Simple Facebook Connect installed on about 6 wordpress sites. I have no problems with 5 of them. I created an app as I have always done on Facebook. I use my App ID, Key, and Secret and put into the SFC settings page. Now, when I return to my wp site, I click on FB connect button and it displays a pop-up box that asks for access to your wall...but never registers the user on my site. The fb box goes away and the website is still sitting on the home page waiting for you to login, register or click on fb connect.
Please advise. Thanks otto.
