I have fresh installation of sitecore and have just added only one content into sitecore content tree. Whenever I click on presentation tab and try to preview "mypage" content "Tracker.Current is not initialized" error is displayed. But my home page preview is working fine. What is the issue here. Sitecore 8.2 is used.
When I've seen this issue before it's often been caused by Sitecore being unable to access MongoDB to store analytics data. (As mentioned in the comments above)
That may be because:
- The connection strings for access to Analytics data in MongoDB are not correct.
- The MongoDB service that the connection strings point to is not running.
- Some sort of firewall or networking issue is blocking connectivity between the Sitecore server and the MongoDB server.
Since you say it's a "fresh install" my guess is that the connection strings aren't correct. They're probably still the default values. So you should check the contents of the
ConnectionStrings.xml file in the
Website\App_Config folder, and make sure the connection settings for the analytics data are right for your MongoDB instance.
Or, if you don't want to run MongoDB and don't need the analytics-based features in Sitecore you can turn it off by adjusting the configuration of Sitecore to disable xDB.
