I am currently enabling xDB on an Sitecore 8.2.5 install that has recently been upgraded from an 8 initial release. It has never had xDB enabled. I'm getting some issues where data appears to be added to the mongoDB, but when I access the any of the reports I'm getting 404 errors:


Log files don't to show anything out of the normal.

The pages where I see this are the custom analytics graph on the launchpad as well as in the experience analytics dashboard.

I don't really understand why this is happening. The xdb remote processing configs are disabled, the route exists in the routes table:


Has anyone seen this error before? Thanks in advance!


Further on investigation it appears that there isnt any data in the sitecore analytics Facts or Dimensions tables. The following error is in log: enter image description here

I have also started from a clean set of MongoDB's and SQL analytics db.

  • Hey Ahmed, yup I've tried this. I have compared the vanilla configs and I'm not seeing any differences associated with analytics. I have also compared all the Sitecore binaries and the /sitecore folder using winmerge and am also not seeing any notable differences.

Remove all duplicate SqlMappingEntity elements from your configs and see if this helps.

  • This almost solved the issue as we did have duplicates. The actual issue was related to a customized DefaultHttpControllerSelector which for some reason has blocked access to any routes within the analytics area. The customisation of the httpcontrollerselector was similar to: link
