In the web.config I've the

enableTracking="true"

If I set to false it works but there's no Tracking

Answer 1

There are multiple factors that can contribute to the issue you are experiencing. To simplify and summarize comments given previously, you need to be sure that:

1. MongoDB is running
2. Your Connection Strings properly set
3. Sitecore License has xDB added
4. Xdb.Enabled and Xdb.Tracking.Enabled are both set to "true"
5. Analytics.ClusterName in Sitecore.Analytics.Tracking.config is a proper hostname
6. Verify you have VisitorIdentification tag added (to weed out robots)

The first thing we need to check is to make sure Mongo DB is installed and Mongo DB service is started.This fixed the issue on my machine.
