I am running the Platform theme by Pagelines. The box to tick when you want to be notified of follow-up comments doesn't appear in the right place in Firefox and Internet Explorer with this theme. The box to tick appears next to the Post Comment button and yet the text whcih says "Notify me of follow-up comments by email" appears on the next line below it. So it is out of place.
In Chrome it is even worse. The box to tick is underneath the Post Comment button itself and you can't even click on it at all before the Post Comment button is blocking it.
I think this is a Jetpack feature because it comes up as a setting under Discussion Settings under where it says "Jetpack Subscriptions Settings"
I hope this can be fixed please. Best wishes.
