I have exactly the same problem on one of my websites on the other I installed it yesterday and it works fine??
I am having the same issue!
Hi,
What host(s) are you folks using? Do you have any other plugins enabled? Any special setup?
Feel free to either respond here or send in a support ticket with this info from the link on http://jetpack.me/support/
Thanks,
Tim
I got it working! I had to deactivate buddypress to do it. Some other people had to deactivate their cache plugins also.
Oh and, once you’re connected to wordpress.com you can reactivate your plugins and jetpack will still work. It’s just the redirect url that has issues.
Hope that helps!
@artofthewrittenword, thanks that worked for me too.
