Hi Naresh,
First check that the user is correctly created in the database that the web server connects to. From your description it is not clear it is the same database that you use in your development environment. If it is the same database, you must remember that users are assigned privileges with a location as well, e.g. user@localhost, in MySQL, so if web server are accessing the database from another machine, privileges need to be assigned for that the user in the database for that IP address (of the web server), e.g. user@192.168.0.15.
Lets assume that you have verified that your user and the privileges are all okay for the database and the error message persists. The next step is to reestablish the production environment on the web server. See this description in the ScriptCase help:

Basically, what you do is specifying the database, username and password for each of the connections that you have used in the development environment. When you deploy your project this always have to be specified, as the production environment will not know about what your connections pointed to in your development environment.
Normally, you would only have to set-up the connections in the production environment once, but I have had occasions where I had to set it up again after which the error mentioned would disappear and everything work as per normal again.
