I recently saw an update flag saying that I needed to update various plugins on my site(including the Jetpack plugin.)
I've updated the others, but I am nervous to do anything with the Jetpack plugin, because last time I was having site issues, someone on this forum advised me to deactivate/reactive all my plugins, and when I did that with Jetpack I lost all my subscribers for about a week! (Until the wordpress.com people could restore them for me.)
I'm afraid to mess with Jetpack again, even for an update... because I can't afford to lose any more time where new posts aren't being sent to my subscribers. Can anyone tell me whether updating Jetpack will screw anything up with my site, my stats, or my subscribers?
