I’ve just set up a new site, I’ve installed Simple Press which is working nicely and I’ve also installed the plugin wp social login so that visitors to the site can easily log in to post comments etc with their twitter/facebook/tumblr account. This plugin works fine for general site login and also for posting comments on the site however when trying to log in via the forums there seems to be some kind of redirect problem which results in the user being given a blank page.
You can test this via using one of the twitter/fb/tumblr login buttons you see on our forum page here http://slingerstv.com/forums
