Hi,

Our customer sent me Umbraco project (backup of files and database), I created site in WebMatrix and it worked fine. Later we realized that DB backup is older and we restored database from backup as another database. I then changed DB settings to new restored database, but I get following error, it looks like it is related with cache built by Umbraco.

There is solution to clear the cache, Delete/Rebuild umbraco based website cache from direct url: http://<;

If I try this solution, it goes to Login page and it does not recognize my earlier logins. (Old backup and new backup has extact same users and password).

Any solution or procedure to switch database? Everything is same, except some more content was added in newer version.

Thank you all for your help.

Regards...
