Hi,

I did one web-site in asp.net. I have published and I checked in IIS everything works fine. But When I upload into my web domain. I am getting following error.

Error:

Section or group name 'system.web.extensions' is already defined. Updates to this may only occur at the configuration level where it is defined

What would probably help here is to see the full content of your web.config file as it is likely that there is a duplicate definition present there.

Alternately, a definition may exist within the web.config that is previously defined within a superceding definition in the server configuration of your web-host.
