It was a reply to the @dosbiner post about our migration services. We could migrate the data to a dev shop for you, then let you install the new theme, then migrate all the data again at the end with a service.
Hmm some of those are really old. Did you update from 1.4 or 1.5 at some point? But, no, its not normal, we condensed the stats modules into one module a while back, but the updater should have handled it.
Can you sort by installed and not installed and install the stats module. Or you can download it here, https://store.thirtybees.com/shop-modules/statistics/statistics-module
The override in the module itself needs to be changed. But I don't know if you can change it without Kinro doing it, since his modules are encrypted. They should be able to handle it with their support, point them to this thread.
If there is no file, it is not overriden. Did you recently purchase the module? I am pretty sure Kinro supports thirty bees, you might put in a ticket with him.
When you run wamp / xamp on local host it is not as optimized as running on a dedicated environment like a server so its slower. Your issue is the ajax call is likely timing out. You can open your console and manually time the call and see if you seem to be hitting like a 30 or 60 second interval. Up your max timeout settings in the php.ini and you should be good.
You can use this as a general idea, https://thirtybees.com/blog/version-1-0-4-has-been-released/
DO NOT RUN THE QUERY SCRIPTS this version does not need any database upgrades / changes.
