I've recently had some problems with the comments box from JetPack. Basically, nobody could add any comments because when they clicked the Submit button a 404 page appeared. No comments would go through. After discovering this and making some research online I thought that this issue might be related to an update of the JetPack plugin. So I've deactivated and activated back this plugin. The comments seem to work fine now.
However, I just realised that all my stats and subscribers are nowhere to be found. I don't care so much about the stats as I am also using Google Analytics but how can I recover all my subscribers? Please help. I didn't think that this is possible with one of WordPress products.
