I have a WP multisite install. (http://dreamfoundry.co.za/) Stats was working just fine until I created a subdomain site where I was planning on working on a new theme. (http://iweek.dreamfoundry.co.za/)
I noticed that Jetpack was automatically connected for the new subdomain site, and showing the stats for the main domain. I disconnected and reconnected Jetpack, and the problem not only persisted, but got worse.
Suddenly the stats for the main site was giving an error. When I disconnected and reconnected Jetpack (as was suggested in the error message) the stats were reset.
The main domain now has a brand new set of stats while the subdomain has the old stats.
Please can someone help me switch them back. I can't simply throw away two years of stats because of a stupid error like this.
