Delivering The Sitecore Experience

Typically developers run into this error in their local environment if they do not have Sitecore Analytics enabled but for some reason have a Sitecore.Analytics.config deployed with the following settings enabled: <!--  ANALYTICS DISABLE DATABASE             Disables the database so that no reading or writing to the database occurs.             Default: false       -->       <setting name="Analytics.DisableDatabase" value="false" /> <!--  ANALYTICS ENABLED             Determines whether analytics is enabled or not.             Default: true       -->       <setting name="Analytics.Enabled" value="true" /> Simply disabling the Analytics DB by setting the Analytics.DisableDatabase to "true" solved the problem. Here is a related blog post about this error.
