When you say it doesn't work, do you mean that the values don't get added to the meta tag or do they just not change? Do other changes that you made using the CMS get saved? Check in the database that you specified in the installation wizard to see if there are new rows being added to store the information being added. Are you getting any error messages when you're trying to change the values or what is the behavior? Are you working on a testing server or on a hosted server? My guess is that the database connection might not be working correctly and you may have to make sure the database server is turned on and working correctly.
