I just followed up on a previous thread I had started, about removing the gray follow box from the bottom right-hand corner, and mentioned this issue (http://wordpress.org/support/topic/removing-gray-follow-box-in-bottom-corner-1?replies=4) - but as I'm not sure if the two are related, I wanted to start a new thread, so it might be easier for others with the same problem to find.
In the past, Jetpack subscriptions has worked fine for me, but now new users who enter their email see a notice that a confirmation email has been sent - but then the confirmation email is never actually sent (I've tested it on five different accounts).
I've recently changed my theme, so I'm not sure if that could have anything to do with it? I've also deleted the "Follow Button for Jetpack" folder (through FTP) in an effort to get rid of the gray follow button - I'm not sure if that's related?
Any suggestions would be greatly appreciated! (And apologies for the double-post, I just wasn't sure if they were two completely unrelated issues.)
