Upgrade to 7.0 - Discussions - Telligent Community

I am getting the following message after we upgrade the site to 7.0 ( from 6.1.1). Any idea what it mean ? and how to fix it ?

Did you apply the 7.0 package on top of an existing 6.x site? An error of the kind "Could not resolve type '...' defined in 'service' attribute" usually means the installation package has been applied incorrectly. Typically that means:

* When applying a hotfix, usually the hotfix has only been partialy applied and there is a mismatch between dlls in /bin/ and the /modules/ folder. Recopying the hotfix installation files on top of your existing community should resolve this issue.

* If upgrading to a new major version, you may still have some relics left from the old version which shouldn't be there. For major version upgrades, we always recommend you start off with a *fresh* copy of the 7.0 site files, and then merge your customisations back into the fresh copy.
