I have attempted to add new twitter and facebook connections in Jetpack
Each takes me to a login to each social media site, I log in, then it shoots me back to my wordpress site to log back into me website. However this is where it hangs up and doesn't let me log into my site. I can go away and come back to my wp-login.php URL address and get in but it never made the connection.
Thanks for your help. I have a completely different WordPress site with Jetpack and I was successful with that (different facebook/twitter accounts used too), so I know what it's supposed to look like.
