The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'.
The 'System.Web.Security.SqlMembershipProvider' requires a database schema compatible with schema version '1'. However, the current database schema is not compatible with this version. You may need to either install a compatible schema with aspnet_regsql.exe (available in the framework installation directory), or upgrade the provider to a newer version.
The above erro is comming when using asp.net membership provider for user authentication etc. And when running whole scripts into server instead of using aspnetdb_regsql.exe.
To solve this error copy the data of schemaversion table into server
